I work at a dog kennel and I have I have found a lot of them out in my dog runs I Just want to make sure they are not poisonous.
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.
