Yellow-masked Bee - Hylaeus
Copyright © 2009 Lynn Bergen

Yellow-masked Bee - Hylaeus
Baiting Hollow, Suffolk County, New York, USA
May 25, 2009
Size: small
Found on a Poison Ivy flower.
A lot of small bees where busy on the Poison Ivy collecting orange pollen.
There were also a lot of these little wasps, I don't think they collect pollen,
not sure exactly what they were doing.

Not wasp.
Genus is Hylaeus, a "yellow-faced bee" in the family Colletidae. You're in good company, most folks make that mistake. This one is likely a male.

"most folks make that mistake"
But how do you tell the difference?
I keep making the same mistake.

Thanks, Eric and Dr. Ascher.

I agree
most likely a male H. affinis or modestus
