Wondering what type of caterpillar these are? Found on milkweed about 75 or so in a group. I’ve seen and photographed monarchs, but these little guys have hair. I didn’t see any eggs and don’t believe monarchs come out in large batches. I know there are limited caterpillars who eat milkweed. Photo taken July 18th in central Connecticut.

Hi Steve,
You are correct that not many caterpillars feed on milkweed, and we had a hunch as to the identity of your caterpillars, but we wanted to find documentation to support our inkling.  Though it is a generalization, butterflies usually lay eggs singly while moths often lay eggs in large clusters.  We could telll that these were moth caterpillars, and we suspected them to be Milkweed Tussock Moth Caterpillars,
Euchaetes egle, though we do not have any images of hatchlings in our own archive.  We found an image on BugGuide that matches your hatchling Milkweed Tussock Moth Caterpillars.
