It’s springtime, and that means the moths in the lab are emerging from their cocoons. Since it is warmer here in the lab, they tend to emerge a few weeks earlier than they would in the wild. This means we get a head-start on pinning and labeling the moths before the field season gets underway.

It is bittersweet, sometimes, when I meet an adult moth I’ve raised from an egg. Knowing that it will be added to my collection as a specimen. Advancing science, but putting an end to a small, fuzzy life. It doesn’t help that I get quite attached to my caterpillars.
But in many ways I embrace this aspect of my work, as the act of pinning and spreading a moth involves considerable skill, practice, and artistry. I am also a firm believer in the importance of scientific specimen collections. Monday mornings are currently my favorite part of the week because that is when I work in UConn’s biological collections, helping to curate the moths. Each specimen has a history and tells a story.

With the emergence of the moths comes the emergence of field gear and enthusiasm. The caterpillar lab can be a dull place during the winter. But this spring/summer promises to be full of adventure, misadventure, and insects. We are starting to receive caterpillars in the mail from collaborators in warmer climates. Moths are fluttering around porch lights at night. Collecting trips are being planned all around the country. I will be breaking out my own collecting lights within the next couple weeks.
For the time being, though, my main duty is pinning my adult moths as they emerge. If you would like to learn more about this task – my friend and I are currently creating an instructional screencast on how to pin a moth – I will post it as soon as it is finished.
