i found your web site and am so glad because i would love to know what kind of moth this is. it may be a common moth, or not. i don’t know but i’ve never seen one before and it is so beautiful. maybe you could recommend a moth field guide that i could use. thanks for any help, and i love your web site.
This is a Columbia Silkmoth, Hyalophora columbia. This species has a coast to coast range in North America, with several different subspecies. We have always liked Holland’s Moth Book, but we believe it is out of print.
