Polyphemus Moth Caterpillar
This thing is huge. It’s as big around as my thumb and as long as my middle finger. Actually, I think it’s pretty amazing that this big, squishy, green blob turns into a beautiful (and quite large) moth. In this case, a Polyphemus moth (Antheraea polyphemus). It’s named after the Cyclops Polyphemus in Homer’s Odyssey because of the large “eye spot” on its hindwings.
