It's not all that often when I find a ladybug (or to be more correct, lady beetle, since it's in the order Coleoptera and not Hemiptera) that isn't the invasive multicolored Asian lady beetle. So when I do, I get pretty excited. I get pretty disappointed when I see invasive organisms dominating the landscape, but when some interesting natives that I've never encountered before pop up, I'm apt to jump up and down in joy (ask anyone who's been out in the field with me). Last month on a botany trip around campus, our group stopped to examine a black locust ( Robinia pseudoacacia ). My attention quickly wandered away from me and I found myself examining the other plants around the black locust, leading me to find some arthropods (woohoo!). One looked like an ant, but my previous experience during the summer taught me not to be too certain, so I caught it and pulled out my hand lens to take a closer look. Imposter! Not an ant, but rather an ant-mimic! This is actuall...

I was going through some of my photos from this past summer (preparing to organize and identify them), when I came across a picture of a tree with some very interesting bark. I had a vague feeling of recognition when I took this picture, but I couldn't quite pin it down. After being a teaching assistant for a botany class this semester, however, I remembered what it was the second time around: American hackberry ( Celtis occidentalis ) . What's the easiest way to remember this tree? Definitely the bark: it's gnarled and warty, with furrows. As the tree gets older, it gets more warty and just a tad bit smoother. It hasn't reached this stage yet, so I would call this tree a teenager.  The leaves are serrate (they have little teeth on the edges), and are alternatively arranged on the stem. American hackberry is found in the West and Midwest, and is relatively common in Ohio. When its leaves fall off in the autumn, you can sometimes find galls on the leaves caused by a Psy...

Regular readers should know by now: I freaking love wheel bugs. Click that picture to enlarge it, sit back, and really look at it for a while. There's no way you'll ever convince me that's not one of the most beautiful creatures in the world. So when I catch wind of the wheel bug being talked about in a negative light, I try to set the record straight. Unfortunately, this time, I could not set the record straight. This link will take you to the website for a local news station serving Pittsburgh, WTAE. The video on the page talks about the wheel bug and how one resident discovered one in her yard and was a little frightened.  Rather than trying to dissuade her of her fears, however, the news team proceeds to FLIP OUT . In what can only be described as an egregious example of shoddy journalism dipped in a vat of ignorance, the video goes on a two minute rampage warning about the dangers of the wheel bug and showing pictures of it to random people on the street, delighting i...

Just a quick post here to highlight one of the more interesting things I've found lately: millipedes that glow under UV light. I've been busy with my Investigative Studies Project, Capstone, and other related endeavors, so I'm essentially stockpiling a lot of photos and information for blog posts during winter, when I won't be finding nearly as much arthropod stuff. You think you have to go to the rainforest to find neat stuff? HA! I took a UV flashlight out to the field a few weeks ago and looked through the leaf litter--it was crawling with these many-legged critters. I could barely contain myself, it was just so neat. There were a few species fluorescing under the light, which is a result of a chemical in their exoskeleton, and the fluorescence was at bright as firefly bioluminescence.  The millipedes were a nice size, hovering around one inch, and had chemical defenses. I grabbed a few to hold in my hand and could smell a slightly sweet scent on my palm after I retu...

I had an unexpected encounter with a centipede today around lunchtime. I walked into the restroom and glanced down at the floor, where I found an inch-long centipede....and I was pretty excited. Unfortunately, it was dead, probably due to being stepped on. If nothing else though, that made collecting it easy for me. Have you ever tried to catch a fleeing centipede? They're ridiculously fast and not an easy catch. After putting it in a plastic bag for safekeeping and eating some lunch, I headed off to the lab, grabbed my centipede ID guide, and threw it under a microscope. It's a little intimidating, measuring out to about an inch long. Earlier this summer, I attended an advanced naturalist workshop at the Edge of Appalachia preserve in West Union, Ohio that focused on the centipedes and millipedes (and isopods), which gave me the skills I needed to tackle Myriapoda identification. It was led by Bill Shear , from Hampden-Sydney College in Virginia, and boy did he know a lot ab...

If you're looking for someone who's passionate about science, you don't have to look any further than Neil deGrasse Tyson, the director of the Hayden Planetarium in New York. This week's Science Video Friday features him articulating why the government funding science is important, even in tough times.

When I think of beetles, what comes to mind are ladybugs, ground beetles, fireflies...maybe stag beetles. All of these are terrestrial beetles and are pretty neat, but why stop at land? There are a number of aquatic beetles that are just as cool, and can be found in rivers, streams, and standing water. I was canvasing my yard the other day when I came upon a wheelbarrow that was full of standing water. I've checked it a few times before for insects, but usually only find mosquito larvae. Last summer I did find one aquatic beetle, but I never got around to investigating what it was. When I checked it this time, however, I found a much more diverse assemblage of creatures.     Acilius mediatus The orange you see in that picture is rust, while the green gelatinous stuff is an egg covering from one of the species of aquatic beetles in the wheelbarrow. Either that or it's algae or something similar. The beetle Acilius mediatus is in the family Dytiscidae, the predacious diving bee...
