sphinx moths

Adults are medium sized to very large, with wingspans ranging from 1⅛″ to 6⅞″ (28 to 175 mm). The body is robust.

The head is large. There are two compound eyes and no simple eyes (ocelli). On some species, the mouthparts are modified into a long straw-like structure (proboscis). The proboscis varies in length, but in some species it is several times the length of the body. When not in use it is coiled up beneath the moth's head. When feeding, the moth uncoils it and uses it to sip nectar. The antennae on most species are thread-like but thickened. On some species they are feather-like (plumose), with branches on both sides (bipectinate).

The thorax and abdomen are densely covered with hair-like scales. On most species there is a prominent tuft of short erect scales at the rear of the thorax and a similar tuft at the front of the abdomen.

The wings are narrow. The forewings are more than twice as long as wide but less than four times as long as wide.

The legs are long and stout, and they are usually armed with spines.

Location: Frenchman’s Bluff SNA

I noticed this brown object on top of the ground while out at Frenchman’s Bluff SNA. I think it may be some kind of moth chrysalis, but not sure.
