Ceanothus silkmoth
Hyalophora euryalus

Observation date: April 18, 2021
Submitted by: fogh8tr@gmail.com
Specimen type: Photograph
Observation notes: In looking at many images of what I believe is a promethea silkmoth what I notice most are the four white stripes. I live at 1,572ft elevation surround by blue oak, white oak, Coast live oak, bay laurel, chaparral, some open grasslands and many seasonal creeks. I get these on my front porch often this time of year.
