Your letter to the bugman:  Hi! I’ve have looked and looked but cannot definitively identify this caterpillar I found a couple days ago. It was in a cottonwood tree. My first thought was a tomato hornworm but the side spots and horn seem too different. Thoughts?

Big Poplar Sphinx Caterpillar

Dear D.E.,
Though this is not a Tomato Hornworm, it is a different species of Hornworm from the family Sphingidae.  We believe it is the Big Poplar Sphinx caterpillar based on the species found Sphingidae of the Americas Utah page.  According to Sphingidae of the Americas:  “Larvae feed on cottonwood and poplar (
Populus) and willow (Salix).”

Your letter to the bugman:  Hi all, love your website, and you always seem to find the answer! I found this rather bedraggled moth on a tree trunk. It was fairly large….like a Sphinx moth, but the head looks wrong for a Sphinx…and underwing of some sort? I couldn’t match it with any Sphinx that I knew.

Probably Clouded Underwing

Dear Mothra,
We didn’t have high hopes for providing you with a species name, though we had confidence that this is an Underwing in the genus
Catocala.  We believe this BugGuide image of a Clouded Underwing, Catocala nebulosa, looks like it might be correct.

Dear Rob,
We suspect your sighting was in Butler, Pennsylvania, not BuTyler.  According to BugGuide data, the Tiger Bee Fly ranges over most of eastern North America, including BuTyler, Pennsylvania.
