Hubbard's Silkmoth Caterpillar

Hubbard’s Silkmoth Caterpillar

Good morning Jonathan,
This is a pre-pupal caterpillar from a moth in the genus
Sphingicampa, formerly Syssphinx, and we suspect it is most likely a Hubbard’s Silkmoth, Sphingicampa hubbardi, though another species, Sphingicampa raspa, is also found in Arizona.  According to BugGuide, the Hubbard’s Silkmoth:  “Larvae feed on Wright’s acacia, honey mesquite and catclaw acacia.”  They are not poisonous.
