Hesperapis sp - Hesperapis

Hesperapis sp - Hesperapis
Anza-Borrego Desert State Park, San Diego County, California, USA
March 24, 1997
Size: BL about 8 mm
This bee was visiting Sweetbush (Bebbia juncea) at the mouth of Hellhole Canyon. Note the two triunguluns on the flower beneath the abdomen. Probably these are of Ripiphorus rex (Ripiphoridae) since we saw a small colony of R. rex females ovipositing into these flowers the previous week. The bee shows no wing venation, but I suspect Hesperapis because of the long hind basitarsus.

Nice pic.
Can you submit a closeup of the Ripiphorus larva? It could be placed on that page and it would be a nice addition. We have hardly any images of larvae.

Triungulin
Hi Beatriz,
I can post a small photo of these triungulin. My photo is 1.5 inches square. I don't know how they will appear on BugGuide.

How should I post? They definitely are triungulin, the free-living hypermetamorphic first-instar larvae of some beetle group. I am making an educated guess that they are Ripiphorid rex triungulin because we saw and recorded females of that species ovipositing into the flowers of this bush the previous week. But it still is only a guess.

Let us hope...
There is one image of a triangulin in the guide.
It would be very nice if we can add yours. I took the liberty to use a thumbnail on your other image rather than just the number. I think that it looks better that way and I hope that you don't mind.

Probably it would be best...
to post the image to Coleoptera for confirmation.

Hesperapis
Thanks for the identification, Dr. Ascher. I've wondered about this bee for a long time.
