What’s this teal caterpiller
I thought I sent this to you back in June but could find no answer. Found in Detroit area in June. Looked everywhere for a picture of it to no avail. Any idea?
Thanks, Chris

Hi Chris,
This is a Forest Tent Caterpillar, Malacosoma disstria. Although a gregarious feeder, this caterpillar does not form a tent. It is occasionally a pest, feeding on aspens, gums, maples, oaks, and many other forest and orchard trees. Caterpillar is found April to June. Here is a Florida site with information aplenty.
