Eucera (Synhalonia) sp. - Eucera -

Anza-Borrego Desert State Park, San Diego County, California, USA
March 5, 2004
Size: BL about 15-16 mm

This beautiful white-furred bee with very long antennae was found on Desert Lavender (Hyptis emoryi) in Bitter Creek Canyon. I suspect Eucera (Synhalonia).

I would agree.

Early date suggests that as well. That genus has gone back and forth with "Tetralonia," so you might wait for Dr. Ascher to give his verdict. We could both be flat out wrong, too!

I also agree

Eucera (Synhalonia) male.

Most "Tetralonia" including all New World species described therein are now placed in other genera.

Eucera (Synhalonia) males

Thanks so much, Eric and Dr. Ascher, for identifying this bee. Males in the Synhalonia group are certainly large, really furry, most attractive and exotic with such long black antennae.

Too many Eucerini!

Thanks for your information, Eric. Except for the very white vestiture, this bee looks like a E. (Synhalonia) that is so identified. But there are too many genera in Eucerini that occur in the southwest to trust my judgement. As you say, it is a very early bee as are so many Synhalonia. Actually, one of them is called E. primiveris!
