Blue (Subfamily Polyommatinae) Butterfly Indentifcation Help
Hello to the Bugman and friends,
I took this picture about a year ago. I believe it is a member of the Gossamer Wing Butterflies (Family Lycaenidae), specifically of the Blues (Subfamily Polyommatinae). I am unsure of the species though. If it helps to narrow down specific species, this picture was taken in Bellingham, Washington. I saw a posting about similar species on your wonderful website already, but the picture was of a newly hatched specimen. Hopefully my attached picture would be of some help. Thank you for the help.

Hi Jonathan,
What a beautiful photo. We believe this is a female Spring Azure, Celastrina ladon, but the Blues are very difficult for us to distinguish from one another. It might take a genius like Vladimir Nabokov to disect their tiny genitalia to be certain.
