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...

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, ...

A Portfolio of Historical Insects

Image
I had some extra time after work today, which I used to visit Marietta College's Special Collections . They keep scores of old documents, many dating back to when the Ohio Company of Associates first established Marietta in 1788 as the first settlement in the Northwest Territory. What I was after today, however, had an Entomological bent to it. A young Hildreth, via Wikipedia . Samuel Prescott Hildreth, a doctor who lived in Marietta during the early to mid-1800s did some of the first work in Ohio studying insects. He was a naturalist and published the first observations of the periodical cicada's 17 year life cycle, which is what I was after. I didn't find any of his cicada papers, but the librarian did bring me a book he wrote and illustrated, entitled " Portfolio of Insects ." This book includes paintings by Hildreth of various insects from Marietta and elsewhere in Ohio. When I first opened the book, I was greeted with beautiful illustrations of the tobacco ho...
