From Out of the Blue Pops the Anthophora

From out the blue. And sometimes it's too good to be true. We were visiting the Sunset Gardens at the Sonoma (Calif.) Cornerstone on Sunday--marveling at the brilliant blue floss flowers, Ageratum houstonianum 'Blue Horizon'--when a bee with the...

The Amazing Bee-Parasite Research of Leslie Saul-Gershenz

Evolutionary ecologist Leslie Saul-Gershenz goes places where many have been but few have ever really seen.  Bees and blister beetles, yes. We remember writing about her work in April of 2013 when she addressed the Nor Cal Entomology Society (now...

The Sneaky Cuckoo Bee

You could call it a slacker, a deadbeat, a moocher, a sponger, or a loafer. Or you could call it a cuckoo bee. Take the cuckoo bee, Xeromelecta californica, a parasite of the digger bee, Anthophora. When the female Anthophora leaves its nest to...
