Submitter has sample

Description of specimen

Wing span about 4 inches. Colorful. Furry. Thought it was a bird at first.


Thank you for your report! These are not pest moths, this is our native Ceanothus silk moth, Hyalophora euryalus! They are not commonly seen because the adults are short lived and nocturnal. They are never abundant enough to damage the forest shrubs like ceanothus that their caterpillars feed on.
