Polyphemus Caterpillar

Luna Caterpillar

Hi Barb,
This is a Polyphemus Moth Caterpillar.  It will transform in
to a large beautiful moth.

Ed. Note:
Upon receiving a comment that this was a Luna Moth Caterpillar and not a Polyphemus Moth Caterpillar, we are amending our original identification.  The Luna Caterpillar is picture and described on BugGuide as “Larva lime-green with pink spots and weak subspiracular stripe on abdomen. Yellow lines cross the larva’s back near the back end of each segment (compare Polyphemus moth caterpillars, which have yellow lines crossing at spiracles). Anal proleg edged in yellow.(2) Sparse hairs.
“  The Polyphemus Moth Caterpillar is described on BugGuide as:  “Larva: body large, bright green, with red and silvery spots below setae, and oblique yellow lines running through spiracles on abdomen; diagonal streak of black and silver on ninth abdominal segment; head and true legs brown; base of primary setae red, subdorsal and lateral setae have silver shading below; end of prolegs with yellow ring, and tipped in black.

    This is a luna moth larva (Actias luna) not a polyphemus. You can tell by the absence of the verticle yellow “stripes” that run through the spiracles of polyphemus larvae, not luna.

    Thanks for this clarification. We often mix up these two caterpillars.
