Gray Hairstreak butterfly in the garden

I found this guy drinking nectar on the cilantro flowers!
I've named him Smedley Bo Flylee.

Smedley was doing this interesting thing, rubbing his wings together!
See the video (it's a little blurry at first)

He stayed for a long time, hopping all over the flowers for drinks.

You can see his tongue in this picture!

Then he opened his wings. They just look mostly brown/gray at first!

But then you see there is blue fur on his back!

Here, his tongue is curled!

He visited for a long time. But then he flew off to find more nectar flowers in other gardens!
