I still consider them to be in the bee family even though they do have a greenish tint to them. A few of us out west used to call them 'neon bee's, but there is no official name for them that i know of.
They have a UV looking color to them, but do not glow under UV light. Some are more pale than others, i was going to post some additional examples but i'm having difficulties in photobucket at the moment.
