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...

I'm currently in a scientific imaging class so that I can learn how to take better insect pictures and use Photoshop. Some of the assignments are a bit bland, so I've been trying to spice them up a bit. Yesterday's assignment was to create a flow chart of....anything. With that free reign, I decided to tackle parasitoids and the tobacco hornworm ( Manduca sexta ). After 20 minutes of a Twitter back and forth with Morgan Jackson and Crystal Ernst , I had a name for my subject: Randy. He had two paths to go down during his life--the choice was up to him.  

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...
