Desert Bee - Svastra sabinensis - male

Desert Bee - Svastra sabinensis - Male
Las Cienegas NRA, Empire Gulch, Pima County, Arizona, USA
August 1, 2006
Size: 7-9mm
This bee was working on an AZ Poppy. When I approached and bent over to shoot, it rolled on its side and stopped moving, for all the world as if feigning death. After shooting, I began to stand up and the little critter jumped up and very quickly flew off. "Playing dead" is not that uncommon in verterbrates, but I've never heard of it in insects. Is this a behavior others have noted? Really curious as well about the ID.

Moved from Svastra.

Lynette - that explains it.

Moved from Svastra.

Hi Lynette:
Looks like image is still on Svastra page. Where was it supposed to have been moved?

Puzzled -
Always am puzzeled when I get a message that something has been "moved from X". The message never tells you where it's been moved TO??? Must be missing something???

sorry Bob,
what happened was that the genus was previously under the wrong tribe. I moved all images/genus/species over to the correct tribe. I know the message looks did this move from Svastra to Svastra!

Lynette - that explains it.

Moved from Diadasia.

Svastra, not Diadasia
This is a eucerine male (=long-horned bee). Diadasia have shorter antennae and differently shaped marginal cells. This is a member of the petulca species group of Svastra (Epimelissodes), most likely S. sabinensis sabinensis (Cockerell)

Many thanks for the correctio
Many thanks for the correction John. I appreciate the education on this one. I learned something new.

Thank you
John for your input. Sounds like you know this group of bees very well. Hopefully, an editor will make the appropriate changes from Diadasia to Svastra s.

You can move your own images, too
First click Tag. A thumbnail of the image will show up in the upper-left corner of the screen.
Next, go to the place you want it to go, then click on the Images tab. You should see a link for Move Tagged Images.
Click that link, and the image will be moved to that place.

I am pretty sure this is a Di
I am pretty sure this is a Diadasia sp. I have seen them curl protectively although never to the point of playing dead.

I agree.
Diadasia is a very common genus in Arizona.

Anaphora sp. (Apidae)

about Anaphora. Doesn't seem to be in the guide in any form. Googled images and a bunch of stuff came up, non of which resembled an insect, let alone a bee.

The name would be
Anthophora, but I'm not sure that's what it is. We should wait for some of our experts to weigh in.

Anthophora sp. (Apidae)
yes, that was my typo late at night.

to Josh, Stephen and Adalbert. The information I was looking for. Indeed, it is a wonder why a bee would feign being dead.

As far as ID...
I couldn't tell you, but feigning death is a pretty common occurrance in the insect world. I have observed it many times with click beetles (Elateridae) and leaf beetles (Chrysomelidae), but never in bees, so I find it intrigueing because with bees so well capable of making escape flights, you'd think they's ahve no use for playing dead. Intersting.

I agree with Josh
I agree with Josh, Beetles use this defense because it takes them so long to lift their elytra and get away. A variation of playing dead is how, I have many times seen a leaf beetle sort of "go limp" and roll off the leaf, as soon as it realized I was looking in its direction, or saw my camera lens moving toward it.

It is interesting to ponder playing dead among bees...

Pollen rapture?
Is this a concept? I've often thought bees seemed high when immersed in a flower, though it doesn't happen all that often. Usually when I've experienced this, the bee has her face planted and out of site, with the butt up and/or assuming a curled position like this one.

Ah, memories
You're helping me relive memories of the sixties!
