A bee mimic moth? There's a small green wasp (I think) in the flower, coming out, but hovering in the lower left is a very polite insect that just waited for the wasp to get out. Hard to see in the picture but it has long hooked antennae. (Maryland, July, cucumber blossoms)
It actually is a bee as well; both appear to be in the family Halictidae (sweat bees) - see http://tinyurl.com/mfvb33 and http://tinyurl.com/ox2cb4 for examples.
Neat! Thanks!
