California Hairstreak? - Satyrium sylvinum

California Hairstreak? - Satyrium sylvinum
Sunol Regional Wilderness Area, California, USA
June 13, 2006
I don't know what this is. The closest thing I can find with this pattern is maybe a very worn California Hairstreak. It'd definitely something in Lycaenidae, but it doesn't have enough spotting to be a copper or a blue. I'm stumped. Any help is appreciated.

Moved from Satyrium.

Moved from Butterflies.

It looks like it might be a worn Western Tailed-Blue (Everes amyntula) that lost its tail.

Wing Spot
The colors on the wing spot would need to have the black on the outside, not on the inside for a tailed blue, but I could be wrong. I think it's something that has lost its tail

You're right, maybe Sylvan Hairstreak (Satyrium sylvinus) is a another possibility.

I agree with Satyrium sylvinus ... minus a tail.

Thanks for the ID J.D.

I'm going to move it to the genus level, since further identification seems unlikely
