Diadasia -

Santa Fe Dam Recreation Area, Los Angeles County, California, USA
April 28, 2007

Loading pollen in Opuntia littoralis .
P.S. After Eric's comments I looked at some more of these, also at an illustration in Michener for D. rinconis (p.154, (1)), and feel confident about at least the genus.

The species det. needs rechecking

on all the potential australis californica as these are very similar to D. opuntiae.

Until these two species can be critically separated it is safer to identify these as D. australis species group = cactus Diadasia

This reminds me

of taking two Diadasia specimens to Doug Yanega last year. He identified one as D. australis, the other as D. rinconis.
Perhaps there could be another species in the same general area?
I'll try to get some specimens this year. Perhaps more than one species uses the big ground nesting area at Santa Fe Dam?

Probably.

That genus is definitely the dominant cactus pollinator....

Thanks, Eric-

three species of cactus in this alluvial scrub community; I'll try to see who else is in those flowers.
