Here's your Bug of the Week! If you can identify this insect, please post your answer in a comment below. I'll share the answer next Wednesday, along with another challenge.
The big, fat caterpillar in last week's challenge was a polyphemus moth caterpillar, Antheraea polyphemus. This species overwinters in the pupal stage, usually by hiding in the leaf litter. People often find the mature caterpillars in the fall, as they prepare to spin their cocoons. This week's shout outs go to Moni and Jeff for correctly identifying the caterpillar.
