Tiny fly on cactus needs ID - Leucopis bellula

Tiny fly on cactus needs ID - Leucopis bellula
Fullerton Arboretum, Fullerton, Orange County, California, USA
December 9, 2009
Size: ~4mm (guess)
This one was towards the top of a huge, high cactus, and I couldn't get close enough to get a good shot. It's sitting at the end of a needle, as the last image shows.

Thanks for the page and the moves, John.
I've taken care of moving the others which were recently IDed.

Leucopis bellula
Hi - looks like I'm a year late! This is Leucopis bellula Williston - known predator of cochineal. The spots of tergites 3-5 are distinctive for this species.

 
Great! Thanks for the ID and the info, Steve.
I figured this fly had something to do with cochineal, then found it later on other plants. It's good to know for sure.

looks generally
like a chamaemyiid, but I can't see enough detail to be totally sure

 
That's it, Keith. And it's Leucopsis sp.
Got some better shots today. Fly is associated with cochineal, and I've been after one for some time. Cochineal is all over the back of the cactus where I shot the fly. More to come.

 
Thanks, Keith.
Should I frass these?
