Yellow-faced Bee
Hylaeus basalis male. The males are odd-looking with the swollen antenna base and yellow face, yet the females are entirely black - not a mark on them.

thanks Lee
Yes, I thought these swollen antennal bases were interesting. I wonder if this trait is common in males across the genus?

Swollen antenna bases
I haven't studied all the species across Canada. Just so happens this one is present in Ontario. Some of our other males have slightly swollen antenna bases and 2 have some white color on them, but none that I know of have the size or bright orange of H. basalis. He's such a comical-looking character!
