Sphingicampa Caterpillar

Sphingicampa Caterpillar

Hi Neil,
You have correctly identified the genus
Sphingicampa, but according to BugGuide:  “Eight species occur in America north of Mexico” and they all have similar looking caterpillars.  BugGuide reports three species in Arizona, including Sphingicampa raspa, and we do not have the necessary skills to say for certain which species you encountered.
