Day Tripping to Adams County

If you have ever spent time with me, you probably know that I love Adams County in southern Ohio. Adams County has some of the most fantastic and unique nature in the state of Ohio. Last week I traveled to Adams County with two fellow naturalists from Ohio University—Olivia Brooks and Alayna Tokash—in order to do some botanizing, herping, and birding.

Out of the several places we traveled to, the favorite was Lynx Prairie. Lynx Prairie is a public preserve that is owned by The Nature Conservancy, and is a location I've written about extensively on this blog. To get a general overview about the nature and history of this famous preserve, check out this link: Lynx Prairie Posts. Lynx Prairie is a system of 10 xeric short grass prairies that are of varying sizes. There is a whole host of interesting and rare species that call these "pocket prairies" home, and so I wanted to share a few of the highlights from my most recent trip!

I'll begin with this inconspicuous flower. This is Slender Ladies'-Tresses (Spiranthes lacera). The ladies'-tresses is a group of orchids with a white inflorescence that typically inhabit prairies or prairie-like habitats. There are 9 species that can be found in Ohio, with 3 of those species being state-listed. The Slender Ladies'-Tresses is one of the more common of the Spiranthes species in Ohio.

The ladies'-tresses can be a difficult group to identify down to species. To identify a ladies'-tresses, you should first see if the flowers are arranged in a single-spiral (such as the Slender Ladies'-Tresses), or a double spiral (like the Great Plains Ladies'-Tresses). After that, you have to carefully inspect the flowers. There are several single-spiral species that can be found in Adams County, but the flowers of each species differ slightly. The Slender Ladies'-Tresses has a characteristic green labellum (or lip), which can be seen above. If you want to read about some of the other species of ladies'-tresses that can be found in the prairies in Adams County, check out my previous post: Spiranthes Orchids at Blue Jay Barrens.

The most exciting plant find of the day—and a lifer for yours truly—was the unassuming succulent pictured above. This is False Aloe (Manfreda virginica). Although common in the southern US, False Aloe is extremely rare in Ohio, where it can currently only be found in Adams and Highland Counties. False Aloe has an extremely interesting history in this part of the state. False Aloe thrives in dry prairie openings, which is currently a rare habitat in Ohio. But between 8,000 and 4,000 years ago, the world entered a very warm period called the Hypsithermal. Ohio became very dry and hot, resulting in the prairies of the west extending into Ohio. False Aloe—a plant of the south-central part of the United States—is thought to have invaded northward into these new Ohio prairies during this time, where it thrived. 

When this hot, dry period ended around 4,000 years ago, the forests began to recolonize Ohio. False Aloe found itself suddenly restricted to the dry limestone barrens of southwest Ohio, which were already thousands of years old. Originally kept open during the last ice age by megafauna like the Mastodon, these barrens were now being kept open as a result of fires set by the early Native Americans in the region. False Aloe became the dominant plant in some of these limestone barrens, and one European settler from the early 1800's even made reference to an "agave desert" in the Adams County region. Once the European settlers killed and pushed the Native Americans out of this region, the human-set fires in the prairies and forests of this region ceased and became a thing of the past.

As the 1900's approached, the people living in this region allowed the forest—which had been all but clearcut in the mid 1800's—to come back. The remaining limestone barrens of Adams County that had not been developed or otherwise destroyed began experiencing the effects of natural succession. Red Cedars and Tuliptrees—which had previously been kept at bay by the fires the Native Americans had set for thousands of years—began pushing their way into the barrens. As many of these barrens became forested, the False Aloe found itself dying out in Ohio. Nowadays this species is found in only a few of the protected barrens which are managed with prescribed burns. Sadly, a recent study found that many of the remaining populations of False Aloe in Adams County are reproductively  isolated and inbred. This will only lead to a further decrease in numbers over the next century, as the seeds of inbred False Aloe tend not to thrive. At its current state, the future of the False Aloe in Ohio seems rather grim...

Moving aside from the doom and gloom to something more upbeat, here is a recently-hatched Eastern Fence Lizard (Sceloporus undulatus) that Alayna found hiding under a loose rock. Learning that Ohio has lizards may come as a surprise to many, but Ohio is indeed home to 5 species (Eastern Fence Lizard, Common Five-Lined Skink, Broad-Headed Skink, Little Brown Skink, and the non-native Common Wall Lizard). The Eastern Fence Lizard belongs to the genus Sceloporus, which are collectively known as the "spiny lizards." The Eastern Fence Lizard is the only spiny lizard that can be found in Ohio, where it inhabits the southern and southeastern portions of the state.

Alayna Tokash (Master's student in Ecology and Evolutionary Biology at Ohio University) studies the tiny Eastern Fence Lizard as it perches on Olivia Brooks's (Undergraduate majoring in Wildlife and Conservation Biology at Ohio University) thumb.

Eastern Fence Lizards begin mating as early as late April here in Ohio, and the first round of eggs begin hatching in June. The individual we found probably hatched out in either June or July. Although Eastern Fence Lizards can live 3-4+ years, most don't make it past their first year due to depredation or other such life-ending circumstances. Hopefully this individual makes it past the initial first year, as chances of survivorship greatly increases in year two. If you want to see what a grown-up Eastern Fence Lizard looks like, take a peek back at my previous "Eastern Fence Lizards" post.

Only an hour later, I came across another baby lizard that was hanging out in a patch of forest between two of the pocket prairies. This is a recently-hatched Common Five-Lined Skink (Plestiodon fasciatus). The Five-Lined Skink is the most widespread and common lizard in Ohio, but isn't commonly seen due to its secretive nature. Five-Lined Skinks can be incredibly skittish, and they will often dart up a tree, under a log, or under the leaf litter upon seeing a human or other potential threat approach. The Five-Lined Skink, along with most other species of lizards, has another line of defense in addition to great evasion skills. The Five-Lined Skink is able to detach its tail in times of danger. If a predator gets too close, or if a predator grabs onto the skink's tail, the skink is able to willingly detach its tail at one of the several breakage points along the tail. 

When the tail becomes detached, it begins to wildly thrash about, which—if all goes according to plan—will surprise and distract the predator, giving enough time for the skink to run away. The Five-Lined Skink that I caught had already used this defense earlier in the summer, as can be told by the healing stub of a tail. Amazingly, Five-Lined Skinks, and other tail-dropping lizards, are able to regrow their tail over time. The catch: they aren't able to regrow the bones in the tail, and are only able to grow a rod of cartilage that takes the place of the bones.

Lynx Prairie is a great location for Five-Lined Skinks. The Five-Lined Skink exploits edge habitats, which are areas where two different types of habitats meet. They prefer edge habitats in which a forest meets some sort of disturbed open habitat, especially if such an area offers plenty of rock and log objects to bask on and to hide underneath. There are copious amounts of edge habitat at Lynx Prairie, offering plenty of appropriate areas for Five-Lined Skinks to inhabit.

One of the most unexpected finds at Lynx occurred when Alayna flipped a small piece of wood. Underneath this tiny piece of wood were two Long-Tailed Salamanders (Eurycea longicauda). The Long-Tailed Salamander was something of a nemesis species of mine for the longest time. They can be found throughout Ohio, except for the northwest quarter of the state. They can be relatively common in near streams in moist forests, but they tend to hide pretty well under rocks and logs, and in crevices in the ground. Despite looking for them for several years, the Long-Tailed Salamander evaded me—until this year, that is. This summer I've seen several Long-Tailed Salamanders, with these being number 3 and 4. As their name implies, the Long-Tailed Salamander has an abnormally long tail when compared to other Plethodontid (lungless) salamanders. In fact, a Long-Tailed Salamander's tail makes up approximately ~60% of its entire body length.

Visiting Lynx Prairie always makes for a fantastic day. However, this trip decided to give me two rather unpleasant surprises. Somehow while in the cedar barrens, I managed to pick up dozens and dozens of tick nymphs. In fact, I ended up pulling 87 tick nymphs off my body that day, and also got 40+ chigger bites as well. I guess that's the price you have to pay to see neat things?

The Red-Backed Salamander, Plethodon cinereus

I've been wanting to do a big post on a species of amphibian that is near and dear to my heart for awhile now. With the semester coming to an end, I've finally gotten the chance to write it. This post is all about the Red-Backed Salamander, Plethodon cinereus. My aim is to give a general overview, with some interesting detailed bits, of this incredibly common species. Why is it so special to me? P. cinereus is the first species I've ever had the chance to do real research on. Starting back in the fall of 2014, I began a job as an undergrad research assistant at Ohio University. I work in Dr. Shawn Kuchta's lab under Maggie Hantak, one of Dr. Kuchta's Ph.D students. It's been an incredibly fun, and incredibly educational, experience so far. I'll talk more about her research and what I do at the end of this post.

That aside, let's move on to some basics! Be warned, this is going to be a really long post.

The Red-Backed Salamander, Plethodon cinereus, is a terrestrial species of Plethodontid salamander. As with all other salamanders in the family Plethodontidae, the Red-Backed is lungless. Since they lack lungs, respiration instead occurs across the skin and the lining of the mouth. For these salamanders to breathe correctly, they must remain moist so gas can be exchanged freely across the cells in the skin. As a result, desiccation (drying out) is a constant threat to this salamander. In order to remain moist, they must inhabit areas that meet a certain threshold for moisture. These salamanders can be found in deciduous forests, mainly under rocks and logs where moisture is retained. When it is wet enough, they will travel throughout the leaf litter on the forest floor in search of food. During the summer months, when the heat dries out the top layers of the forest floor, P. cinereus will move into the ground, using old worm burrows or possibly making burrows itself.

P. cinereus is an incredibly abundant species in the forests of the Northeast part of the US, and it can be found in nearly every county here in Ohio. In fact, P. cinereus is thought to be the most abundant vertebrate species in the Northeast quarter of the US. They can reach densities of 2.8 individuals per square meter in good habitats, making this species more abundant than birds and mammals combined. In addition, there is some compelling evidence that the 2.8 individuals per square meter number is actually an underestimate; it might be double that number (See Semlitsch et al., 2014)! It is important to note that the bulk of a given population of Red-Backed Salamanders lives below the surface, so trying to accurately estimate a population is difficult when you can only find those individuals who are on the surface (See Taub 1961). When Maggie and I travel to a good location in Northern Ohio, we can normally find at least one individual under every rock or log you flip. It's amazing to think that all those individuals we readily find under cover objects represent only a fraction of the individuals actually living in that location.

The two common morphs of the Red-Backed Salamander, with the red-stripe morph on the right, and the lead morph on the left.

One of the really interesting characteristics about this salamander is its color polymorphism. Polymorphism is where there are two or more clearly different phenotypes (an individual's set of physical traits) in a species. Generally speaking, P. cinereus exhibits three color morphs. First is the red-stripe morph (pictured above on the right). This is by far the most common morph. The second most common morph is the lead (or lead-backed) morph (pictured above on the left). The third morph is the erythristic morph, which is very rare. The erythristic morph is essentially all red with a creamy white stomach. In addition to these three morphs, there are several other rare color anomalies: iridistic, albino, leucistic, amelanistic, and melanistic. You can read more about the different color phenotypes in J.D. Moore's paper here.

As stated previously, the red-stripe morph is by far the most common, especially in Ohio. There are, however, many polymorphic populations. Northern Ohio has a relatively high density of polymorphic populations, where one can find both the lead and red-stripe morph (and occasionally the erythristic morph) all living together in the same location. The ratios between the morphs vary according to each site. Interestingly, there are a few all-lead populations in Ohio, such as the population on South Bass Island. This is not a common occurrence by any means.

There is an extreme amount of color variation not only between color morphs, but also within the morphs and anomalies. At some locations we visit, the red-stripe morphs have a very bright and well defined red stripe. At other locations, the red stripe is very mottled and dull with high amounts of black across the body. On the other side of the coin, the leads at some locations are a very dull and subdued black, while other locations have very iridescent and beautiful leads, like the one pictured above.

Unlike many salamander species, P. cinereus does not have an aquatic larval stage. The entire life cycle is terrestrial, and that means we run into many juvenile individuals when in the field. And the juveniles are cute. Extremely cute. Pictured above is a small (yes, small) adult red-stripe individual next to a juvenile lead individual. Many of the juveniles we find could easily fit on a penny.

Most, but not all, salamanders lay eggs, and this includes the Red-Backed Salamander. When we measure the salamanders, we are able to see the eggs of any pregnant females. These eggs can be very pronounced, as the photo above shows. If you count carefully, you can see a total of 8 eggs (the white blobby things in the abdomen) in the individual above. As mentioned earlier, while many salamanders have an aquatic larval stage, the Red-Backed is completely terrestrial. The eggs are laid in a protected area, mainly in rotten logs. There is a larval stage, but this stage happens completely in the egg. Upon hatching, the juveniles are fully developed and essentially a smaller version of the adult.

How do you tell the sex of a Red-Backed Salamander? There are a few differences between the two sexes, but the easiest way is to look at their heads. Females have a very round snout. Males, on the other hand, have a very broad, square-like snout, which you can see above. Another feature to look for is the presence of cirri. Cirri (singular cirrus) are a fleshy downward extension of the upper lip. Cirri function as chemoreceptors, and the males use these for a multitude of reasons, most commonly to sense out a potential mate's pheromones. You can see the cirri on the male above; they are the two tiny, mustache-like extensions hanging down on either side of the snout. As always, you can click on a photo to view a larger version of it.

One of the incredibly interesting characteristics of salamanders is their ability to regenerate whole limbs and parts of major organs. It's a tough world out there, and salamanders can lose parts of their body due to predators, but also due to fights with larger salamanders. Red-Backed Salamanders are known for being fiercely territorial, and they will defend their territories against many different intruders like the Northern Ravine Salamander, Spotted Salamanders, or centipedes, occasionally resulting in the loss of limbs. The tail is the part that is most often lost, like in the individual above. When it comes to tails, salamanders are like lizards. When in a situation with a predator, the Red-Backed Salamander will wave its tail in an attempt to get the predator to go after that part instead of elsewhere. As soon as the predator latches onto the tail, the tail pops off giving the salamander time to escape. The tail wiggles violently for a short bit to confuse the predator even further in order to hopefully allow a safe escape for the salamander. Salamanders can regrow legs in only 7-10 weeks, but tails take a little long due to their size and how much actually comes off. The individual above (who was found in the Fall) probably has a fully regrown tail by now.

While the Red-Backed Salamander is a prey item for many other animals, it is still a ferocious predator itself. I'm currently in the middle of a dietary study that aims to find out if there is a difference in the type of food the red-stripe and lead morphs eat. The Red-Backed Salamander eats a large variety of arthropods, although I did find a weird one who ate a mushroom. The photos above give you an idea of some of their usual prey items. On the far right is their favorite type of food, mites. There's an incredible diversity of mite species on the forest flood, and the salamanders will eat many of them. In the center are Springtails, another favorite. On the far left is a pseudoscorpion, one of the more awesome-looking arthropods they eat. In addition, they also consume ants, beetles, assorted tiny wasps, spiders, and more.

One of more interesting individuals we've come across so far this Spring is the one pictured above. We had traveled to a location where around 15% of the population was erythristic (an unusual reddish or orange coloration). While we didn't find any completely erythristic individuals, Maggie did find the one above which exhibits partial erythrism. Note how most of the body is a red-orange, while the stomach is a creamy white. There's too much black on the individual for it to be considered completely erythristic, but you can tell it is definitely not a normal red-stripe individual. If you're interested in learning more, partial erythrism and erythrism in general is covered in the J.D. Moore paper that I linked to earlier in the post.

Several weeks after I wrote this initial post, we came across another interesting individual, pictured above. This is what has been called the "Silver-Striped" or "Silver-Backed" variant of the Red-Backed Salamander. As you can see, the stripe running down the back in this individual is a silvery-grey color instead of the normal red color. Sadly there's not much information I can find on this color abnormality other than assorted photos of similar individuals. Vincent Farallo, an Ohio University graduate student, did tell me that he has seen a lot of individuals like this at Strouds Run State Park in Athens County.

Maggie Hantak measuring a Red-Backed Salamander using a method termed "Mander-Mashing." Seriously. (No salamanders are harmed in this process.)

As I mentioned earlier, I currently have a job as an undergrad research assistant. My job is essentially to help Maggie Hantak, a Ph.D student at Ohio University, collect data at her field sites in Northern Ohio, as well as working independently on a dietary study for her. In a nutshell, Maggie is exploring multiple facets of the evolutionary ecology of the Red-Backed Salamander with regard to the differences between the red-stripe and lead morphs. She's been a wonderful mentor to me and has helped me get involved in real research. I'll be spending the first half of this summer in Northern Ohio as her field assistant, with the last half spent down in Athens to try and finish the dietary study. I'll also hopefully have the opportunity to begin my own research on Plethodon electromorphus, the Northern Ravine Salamander, this summer.  As of October, 2016, I am beginning my own independent project on the Northern Ravine Salamander. Stay tuned for more information in the upcoming months!

I've got several more salamander posts in the works that I'll hopefully be finishing up sometime during Summer, so if you're a herpetology person, stay tuned! Otherwise, I'll be covering the usual interesting things I come across this summer, including flowers, birds, insects, parks and more. Thanks for reading!

Even More Salamanders

I went out herping once again Thursday night (April 3) with some fellow wildlife and conservation biology students from Ohio University. We went to the same place as last time, State Route 356 in Athens County. Sadly, there wasn't any salamander migration going on like there was the other night, but we did find some salamanders and some other interesting things.

Let's start with the star of the night.

This is a Marbled Salamander, Ambystoma opacum. This one raised quite the stir among our group; besides being a lifer for almost all of us, the coloration of this salamander is amazing. This species does not migrate in the Spring, and instead breeds in the fall. We only found this one because we decided to flip a large chunk of concrete on the side of the road.

The Marbled Salamander is uncommon in Ohio. It has been recorded in 26 counties (of the 88), but some of the counties that have no records surely have populations that just haven't been found. For example, Hocking County has no record of them, but I'm sure Hocking County has them somewhere. The thing is, Marbled Salamanders spend most of their year underground, which obviously makes it hard to find them.

These two slender, slimy salamanders are the Eastern Red-Backed Salamander, Plethodon cinereus. These are really common salamanders in Ohio. There are two different color morphs that can be found in Ohio, the red-backed (shown above) and a lead morph (not shown). They are found most often underground and under rocks and logs in moist forests.

Red-Backed Salamanders need a moist environment because they are lungless salamanders. Since they do not have lungs, they instead breathe through their skin, which must be kept moist. Since their skin is so permeable, these guys, like the Eastern Red-Spotted Newt I mentioned a few posts back, are very sensitive to pollutants in their environment as they will absorb them directly into their body.

Okay, so this one isn't from Thursday night. This photo is actually from a few weeks ago at The Ridges in Athens, Athens County. The salamander in question is a Southern Two-Lined Salamander, Eurycea cirrigera. This one was found in a small creek under a rock. This species is found in the southern two-thirds of Ohio. There were actually a couple within a pretty small area of the creek. I found two adults and a juvenile one that still had external gills.

This is not a salamander, if you couldn't tell. Regardless, I love these little guys and wanted to throw one in. This is a Spring Peeper, Pseudacris crucifer, as you can see from the "X" on its back. I've covered more on these guys on another post of my blog, which can be found here if you're interested: Herping: Frogs, a Toad, and More. These were so loud Thursday night (which is when this one's photo was taken) that my ears were ringing for over an hour when I came home.

This is also not a salamander, but I'm still throwing it in! While walking through a swampy area along the road, I came across a small patch of tiny wildflowers. This is the Harbinger of Spring, Erigenia bulbosa. This is actually the first wildflower I've come across this year, and I was very excited when I stumbled across it. As the name implies, this is one of the first wildflowers to bloom in the Spring. I almost passed it; these are so very tiny. Think clover-sized.

Alright, that was a long enough post. Hopefully you enjoyed it! Thanks for reading!

Herping: Salamanders

On Wednesday night, I traveled out to a patch of State Route 356 by the Waterloo Aquatic Education Center in Athens County with some fellow Ohio University wildlife-major undergrads and assorted graduate students to do some herping. What's herping? Well, it's like the word "birding;" herping, based on the word herpetology, is the act of going out and looking for reptiles and amphibians.

With the rain earlier in the day, and the warmer temperatures, the salamanders were bound to be out migrating to their breeding grounds. Typically, salamanders migrate in late winter or early spring when the ground is wet from rain and the temperatures are above 45 degrees Fahrenheit. Wednesday night was one such night. In this post, I will cover the salamander species we came across. The next post will be about the frogs/toads and extras we came across. EDIT: Part 2 can be found here!

The first species we came across, and by far the most abundant of the night, was the Spotted Salamander, Ambystoma maculatum. A large mole salamander, Spotteds can be easily IDed by their two rows of yellow spots running down their body.

Spotted Salamanders mainly live underground in the forest for most of the year, but during wet nights in spring they migrate to annual breeding ponds. After breeding, these salamanders return underground to live out the rest of the year. A long-living species, these have been known to reach 32 years old!

The second most abundant species of the night was the Jefferson Salamander, Ambystoma jeffersonianum. Another species of mole salamander, this species is slate-gray in color, and a tiny bit smaller than the Spotted Salamanders (but not by much). You can tell they are a lot more slender than a Spotted Salamander though. This individual was submerged in a marshy area along the road that was also home to hundreds of calling Spring Peepers.

Jefferson Salamanders, like Spotted Salamanders, spend most of the year underground, aside from when they migrate to their breeding ponds in the spring. The name is in honor of Jefferson College in Pennsylvania (I'm guessing someone from the college had a hand in discovering/naming it). In the photo above you can also see the head of one of the Spotted Salamanders checking out the Jefferson.

This guy is the Eastern Newt, specifically the Red-Spotted subspecies, Notophthalmus viridescens viridescens. We came across a handful, but they were no where near as abundant as the previous two salamanders. However, finding a newt is a good indicator as to the health of the area they're in. Newts have very permeable skin and are, as a result, very sensitive to toxins that make their way into environments. They're also very sensitive to pH changes in water, which Southeastern Ohio has a very large problem with due to acid-mine drainage, where acidic water from mines lowers the pH of creeks, rivers, and ponds to a level where many animals cannot live in them. So it is good news, at least for this immediate area, to find them.

Now onto another, more gruesome, topic. This is a dead Spotted Salamander, one of the dozens we found along the road that were struck and killed by cars. Humans have really hurt salamander populations by building roads through migration routes. Salamanders typically use the same migration routes to the same vernal pools every year. We have built roads that have fragmented their habitat, forcing them to cross dangerous roads in order to breed. Many do not make it, like this one. Please, if it is a warm, wet night in early spring, watch out for salamanders and try to avoid hitting them if you see one on the road. Conservation of our native species begins with you.

I hope you enjoyed the post! It was my first ever herping trip, and I will admit I am hooked. It's incredibly exciting to be walking through the dark down a forested road with only a headlamp and then come across one of these awesome guys plodding slowly along. As I mentioned earlier, there will be another post coming soon (sometime by Sunday for sure) covering the frog and toad species we came across, along with a few extra goodies. Edit: Part 2 over the frogs, toad, and more can be found here!

Some Findings at The Ridges

I went on a hike at The Ridges the other day, which you can read about right here, and came across a few interesting creatures and plants.

This is an Eastern Garter Snake, Thamnophis sirtalis sirtalis. He was lucky; I didn't see him at first and almost stepped on him. This garter was really cooperative with me. He let me get within 5 inches of his face to take some close ups before he slithered away into the forest. Eastern Garter snakes are very common snakes and if you pay attention you'll probably notice one sometime while out hiking. This one was a smaller one, only about a foot long, but they can reach up to three feet or more. Soon this one will be grouping up with other garters to hibernate for the winter.

Ah! A salamander! I flipped over a log hoping to find one, and sure enough there was. This is a new species for me - the Northern Ravine Salamander, Plethodon electromorphus. This is a relatively "new" species actually. It was separated from the old "Ravine Salamander," P. richmondi, now known as Southern Ravine Salamander, in the last decade or two. Northern Ravines are different from their Southern Ravine cousins in their protein composition and their distribution. As a result, information on them seems rocky. Most of the studies done in the 1900's at some point may have included mixes of both species, or one, or the other, so info on Northern Ravine Salamanders is lacking, to say the least. Now that they know it's a new species maybe new research will start separating our knowledge of the two.

Here's another salamander I came across. This is a shy Northern Dusky Salamander, Desmognathus fuscus. He was in some exposed rocks along a stream and when I looked at him he promptly pulled himself into a little crevice and tried to hide from me. ODNR says they are the most abundant of our salamanders. In the northern parts of their range, like Ohio, they prefer small streams (Like where this one was found), springs, and seepages. Interestingly, this species has an immovable lower jaw and the only way it can open its mouth is to raise its head.

You've might have seen one of these, if you pay attention to tiny critters. This is a Red Velvet Mite, family Trombidiidae. I'm not sure of the species, but it's most likely either a Trombidium sp. or a Allothrombium sp. Red Velvet Mites are actually arachnids, like spiders. Many species are very small, but this one was a bit larger than the ones I normally run across; still very small, but large enough to catch my eye from a few feet away. They won't hurt you, unless you're a small insect, in which case these predators will probably be going after you.

These are the flowers of the White Snake Root, Ageratina altissima. This is a poisonous herb. It contains the toxin tremetol, which can poison humans through an interestingly process. Cows will sometimes eat this plant, and as a result ingest the toxin. This makes the milk and meat of the cow poisonous. Humans would drink the milk, and if they ingested large enough quantities of the toxin, would consequently get tremetol poisoning. Before we knew snake root was the cause, we used to just call the subsequent poisoning "Milk Sickness." Back in the frontier days, it killed thousands of settlers, many of them in the Ohio River Valley. Abraham Lincoln's mom Nancy Hicks was actually a victim of Milk Sickness. Finally, in 1928, the official link between Milk Sickness and White Snake Root was pinned down.

Alright! That's all I have for this post. Stay tuned for another post really soon over a couple of "fuzzy" caterpillars I found on this trip.
