I saw this bug on the ground outside my office on 3/20/13 in Alpine, CA. I have never seen anything like it. It looks like a combination of a spider, butterfly, and caterpillar. It seemed to be trying to walk and/or fly and seemed to be having trouble doing either. Is no longer there, so unsure what happened to it. Was quite large-body was about 1 inch, wings were maybe 2 inches.

Hi Jennifer,
This is a Ceanothus Silkmoth, Hyalophora euryalus, and this is not the first time that we have received a letter requesting the identification of a large moth that was compared in appearance to a caterpillar.  You can find more information on the Ceanothus Silkmoth on BugGuide
