What's That Bug? does not endorse extermination

Second Unknown Caterpillar in AZ

Hi there, My daughter found two of what appear to be the same caterpillars as your reader in Gilbert, AZ. We found them on a snapdragon vine in our back yard in Tucson. I have done exhaustive research and have been unable to identify the caterpillar. Just thought you would like another example of the same critter in the same general geographic area.
PS We are keeping them in a quart mason jar with fresh clippings of the plant on which we found them, and hope to observe them through their metamorphosis. Perhaps then we will be able to identify them.

Unidentified Caterpillar

Dear Alicia & Sadie,
We looked through so many Caterpillar images on BugGuide when we received that previous letter that we were seeing cross eyed.  We are no closer than our original guess that it might be a member of the genus
Cuculia, the Hooded Owlet Moths, though we couldn’t find any examples on BugGuide that had those markings.  Also the heads on the Hooded Owlet Moth Caterpillars were not pink like the head on the Gilbert, Arizona Caterpillar.  Your caterpillar, on the other hand, looks very much like this Hooded Owlet Moth Caterpillar in the genus Cuculia that is posted to BugGuide.  Though we may be wrong, we believe we may have your identification correct.

Unidentified Caterpillar

Excellent! I too am seeing cross-eyed after searching in every Arizona caterpillar database I could find online, as well as several for northern Mexico. Thanks so much for being such an awesome resource.
All the best,
Alicia in Tucson

      Dear cakelady,
      The Catalpa Sphinx does have very similar markings, however, we cannot make out a caudal horn in the photos, so we don’t think that is a correct identification.
