Eucerini female - Eucera -

Anza-Borrego Desert State Park, San Diego County, California, USA
May 15, 1997

This large bee was sleeping in a large Cucurbita palmata (Coyote Melon) flower at 8:00 A.M. at Upper Tubb Canyon, elevation about 2200'. I've always thought this was a Squash Bee, Peponapis sp., possibly a sleeping male. Now I am trying to study the group. I find that in Peponapis timberlakei (the most likely species because it's the only species reported where the female collects pollen from C. palmata), the male has a yellow clypeus. Our bee has a black clypeus, so my initial identification was not correct. Now I wonder if it is even a Peponapis sp or maybe just another large furry bee sleeping in a cozy hideaway. Any help will be greatly appreciated.

Thanks so much for the identification, Dr. Ascher. She's quite covered with pollen, but I don't see many grains at all on her hind legs.

Eucerini female

not sure of the genus

what about Svastra (Idiomelissodes) duplocincta?

hard to see the abdominal banding, but the rest of it makes me think Idiomelissodes.

… Doug Yanega, 3 August, 2009 - 6:55pm

the abdominal banding doesn't look right to me

compare:

The clypeus looks too protuberant (flatter in Svastra)

Also the host plant is wrong and the date perhaps too early?

This reminds me of Eucera (Synhalonia) angustifrons, in which the eyes are convergent above
