A Primer on Ohio Millipedes

Image
Millipede - Abacion sp. I've been doing some research lately on a few millipede genera and have found myself lamenting the lack of well-written and accessible resources for millipedes. I have a good enough knowledge base to navigate through the published literature, but it's too inaccessible for general audiences. BugGuide's millipede page is probably the best online resource, but it still lacks good introductory resources for people wanting to learn more about the many-legged critters. You're able to submit a picture, and if you're lucky, someone will help you get it down to genus and maybe tell you how they identified it. Concise keys for the millipedes don't really exist like they do for other arthropods, due to the characteristics used to identify millipedes. It's not like identifying a moth or a beetle, where coloration, pattern, and overall look can go a long way. You can get to Order from a photograph relatively easily with millipedes, ...

The Amber Flame Tree

Image
It has now been a year since my journey to Costa Rica as part of a semester study abroad experience focusing on Biology and Spanish. I returned last May, and one of the things I was most looking forward to was fall: I needed to see some explosive leaf colors. Don't get me wrong, the plants I saw in Costa Rica were beautiful and vibrant green, but it's difficult to compare that with the leaf colors you can see during an Ohio autumn. As fall came and went, I saw some wonderful colors, and gradually came to the realization that one of my favorite trees is the American sweet gum, Liquidambar styraciflua . Even its scientific name is beautiful and rolls right off your tongue, it's fantastic. The leaves of the tree are palmate to be technical, but I would rather describe them as five-pointed stars. The colors of these leaves are astounding and range from green to purple, with yellows, reds, and oranges in between.The maples have nothing on this tree! Leaves of a young tree. Notic...

It's Hard to be a Hornworm

Image
In Ohio, there's a delightfully gregarious caterpillar known as Manduca sexta , or the tobacco hornworm. It's placed within the Sphingidae family, which is composed of the hawk moths. Take a look at the Wikipedia page for the hawk moths: they're all spectacular. Some of the adult moths resemble birds or bees, they're just amazing. To get back on topic, the tobacco hornworm feeds on tobacco (obviously), as well as other plants within the family Solanaceae , which includes tomatoes. This makes them pests to gardeners, which is pretty unfair. Tobacco hornworms develop into some beautiful moths and are quite large, so they're truly a sight to see once they reach maturity. Luckily for me, they also feed on Datura wrightii , a plant within the same family as tobacco and tomato, which grows near my house. I had the fortune of finding a few of the caterpillars on the Datura plant, so I plucked them along with some leaves and placed them in a container in my room. They were...
