A Clearwing Hummingbird Moth

I had been wondering where this little moth was this season as I had not seen it previously.  Early last evening I had taken a drive to a nearby Common Primrose plant to release a Primrose moth that I had captured earlier in the day and it was then that I had spied this clearwing hummingbird moth feeding on some Milkweed in bloom.

I am thinking that this afternoon I will be able to get some more pictures of this delightful moth in a milkweed patch.
