Prickly Pear Borer

Dear Emily,
This Caterpillar looks familiar to us, and we suspect we have previously identified it somewhere in our archives.  It reminds us of a Carpenter Moth Caterpillar in the family Cossidae, but we cannot substantiate that suspicion at this time.  Perhaps one of our readers will be able to assist in this identification.

Update:  November 21, 2018
Thanks to a comment from Karl, we have identified this Prickly Pear Borer.  According to BugGuide other common names include:  “banded cactus borers (larvae of junctolineella and subumbrella) and blue cactus borers (larvae of dentata and prodenialis).”
