Hi,
I have seen these creaturs before but rarely. My friend just sent me your site. This one was almost 2 inches long.
Thanks in advance for your ID help!

Polyphemus Moth Caterpillar

Dear Lynn,
This is the caterpillar of a Polyphemus Moth.  Despite having two prominent eyespots, the Polyphemus Moth was named after the one-eyed Cyclops of Odyssey fame.  Polyphemus Moths are found in all 48 of the continental United States.  Featured Creatures has an excellent posting on the Polyphemus Moth which includes this information:  “Caterpillars are solitary and develop through five instars. Immediately after hatching, caterpillars eat their egg shells (Opler et al. 2012 ). Older instars eat whole leaves and then sever the petioles to drop them to the ground (Tuskes et al. 1996) – possibly to obscure their presence from predators The presence of large larvae on branches overhead may often be detected by the presence of frass (caterpillar droppings) on pavement of driveways or parking lots.”
