Millipede Mystery

Image
My millipede research always seems to throw me into new adventures. Neat information just sort of hangs out in the old literature, sometimes in the form of a new species that no one is quite sure about. The species in question is Chaetaspis albus . Sort of. First, we'll go over the information we have about this species. Chaetaspis albus (no common name, sorry) was described by Charles Harvey Bollman in 1887 ( Entomologica Americana , II, 1887, pp.45-46). It's a millipede in the order Polydesmida and family Macrosternodesmidae. His description was also included in an 1893 publication of his works, which is great, because that means I can post the whole thing here without having to worry about copyright. If it's tough to read, you can click the photo to enlarge it. From Bollman 1893 So there's our information on the original specimen. It's white, less than a centimeter long, less than a millimeter wide, and was found in Indiana under a log. That's a millipede th...

Invasive Insects in Ohio: The Hemlock Wooly Adelgid

Globalization strikes again! The main invasive pests I've been hearing about in Ohio over the past few years have been the Emerald Ash Borer ( Agrilus planipennis ) and Asian Longhorn Beetle ( Anoplophora glabripennis ), but I now have a new one to add to my list: the Hemlock Wooly Adelgid ( Adelges tsugae ). The Hemlock Wooly Adelgid (HWA) is a true bug in the order Hemiptera and is sort of like an aphid. Adelgids suck plant juices out of conifers, and HWA prefers hemlock trees, specially the eastern and Carolina hemlocks ( Tsuga canadensis and Tsuga caroliniana , respectively). This is a problem. HWA was introduced into the US from Asia in the 1920s, first in the Pacific Northwest, and then in Virginia in the 1950s. That was the start of its foothold in the east, and it spread to other states from there, including Pennsylvania and West Virginia. It didn't reach Ohio until 2001, and has spread into about 27 counties since then. Unfortunately, in 2012 it was detected in my home...

What's out there? Compiling a biotic index.

Do you know the insect species that inhabit your backyard? What about a local park or nature preserve? How about your county? These are important questions to think about. If no one knows the animal diversity in their area, then why would they stop to think about protecting that diversity?  Some of the most interesting animals are very specialized and need certain habitats to thrive; without those habitats, they'll disappear. I think we can all agree that nature is important, and having a knowledge of your local species (of insects, mammals, birds, plants, fungi...) is empowering. You can see ecological connections and gain a new-found respect for your fellow organisms, just from being able to identify species and know what's around you.  A Luna Moth ( Actias luna ) soon after emerging from the ground. Its wings aren't yet ready to fly--you can see how small they are. With this topic in mind, I've been working for the past few months on gathering together pictures and i...

Dancing Stick

Image
The species I find in the county never cease to amaze me.  This delightful stick insect, for example, takes a discerning eye to pick out in the forest. "My dream in life is....TO DANCE!" But not really. This guy found me when he started to crawl on a friend during a recent potluck. It's a Northern Walkingstick, Diapheromera femorata , the continent's most common walkingstick. It's about three inches long, but looks bigger because of how long its legs are.  Its limbs are leafy green and its body looks like it's been sculpted straight from a tree, giving it some terrific camouflage. I've been observing it in an insect cage for the last few days and it truly is a remarkable insect. Walkingsticks are the world's best method actors, taking their role as a stick very seriously.  ...which is a good strategy, as birds are liable to pick these guys right off the plants they're feeding on. 

Mission Complete: Skunk Cabbage

Image
A year ago, while I was in Costa Rica studying abroad, I heard about the mythical skunk cabbage, Symplocarpus foetidus . This magical plant was said to flower during late winter and early spring, and to even have the powers to melt snow around it and attract some of the first insect pollinators of the year. After seeing some marvelous pictures of this legendary arum, I resolved to find this plant myself. Unfortunately, I was in Costa Rica. (Yes, I'm aware that this is probably the first time that sentence has ever been said.) By the time I returned to the United States, the flowers were gone. But now, after an entire year, we're in the correct season and all the elements have come together to form perfect skunk cabbage weather. Today, my class schedule even worked out, resulting in my Lower Plants lab taking a trip to search for the prize. Ladies and gentlemen: we have skunk cabbage! As we entered an area with a natural seep to look for the cabbage, we were teased with the.......
