Bagrada hilaris  - Bagrada hilaris - male - female

Bagrada hilaris - Bagrada hilaris - Male Female
Borrego Sink, Borrego Springs, San Diego County, California, USA
October 4, 2008
Size: Female ~ 5.8 mm
This pair were on Jackass Clover in the Borrego Sink. They seem smaller than Harlequin Bugs and the pattern is not exactly the same. I've tried to research the genus of "Little" Harlequin Bugs, Cosmopepla,but none that I could find images of were this insect.

Hello, Lynn,
I've moved this to species. Ron's ID is correct, and it is interesting, though not unexpected, to see this from Borrego Springs. If you find more, send / take some specimens directly to CDFA, perhaps with a remark that Dr. Rosser Garrison has already received specimens.

 
Bagrada hilaris
Yes, we will be on the lookout for this species on our next visit to Borrego. We found several of them, both on 4 Oct and 12 Oct,all on Wislizenia refracta. Thanks for moving to species.

These are hilarious, oops, make that hilaris
Or more exactly Bagrada hilaris.

Check this post, and you'll see that Harmut Wisch went to a lot of trouble to get an ID for these. If you see such bugs again, he'd appreciate a specimen or two.

 
Bagrada hilaris
Yes, that's our pair! And what an interesting tale of how it was IDed. So it's a non-native species--and possibly just recently arrived.

Hartmut Wisch mentioned they especially like to eat plants in the Mustard Family. We found it on Jackass Clover (wislizenia refracta) that is in the Caper Family, very closely related to mustards.

Thanks, Ron and Margarethe, for your identifications help. 'Twould be a hard ID to track down by myself!

 
Bagrada hilaris - Oops
you just beat me to it

 
I should have let you lead on this.
At least, you'd have spelled Hartmut's name right!
