Eastern Tailed-Blue

I love noticing butterflies that I've never seen before, and for whatever reason, this feels especially rewarding when those butterflies are small and easy to overlook. This Eastern Tailed-Blue (Cupido comyntas) was fluttering around in Silver Sands State Park this morning, and it probably wasn't much bigger than my thumb nail, but boy was it pretty:
 

Apparently these butterflies are quite common, but I don't remember ever really looking at one before. Some of my favorite details include those two whispy "tails" on its hindwings, the small orange spots nestled in clean gray, and of course, the brilliant blue when those gray wings open:
 

That blue color means that this is a male, since female Eastern Tailed-Blues are a duller brown/gray (or so I've read). Keep flashing those wings, you pretty little fellow!
