Bug Squad

Diggin' the digger bee... We spotted this female digger bee, Anthophora urbana, zooming in on some zinnias at UC Davis. She buzzed loudly, virtually owning the zinnia patch. Smaller sweat bees scattered.

Meet a carpenter bee. This one (below) is a male carpenter bee, Xylocopa tabaniformis orpifex, as identified by native pollinator specialist Robbin Thorp, emeritus professor of entomology at the University of California, Davis. It's also called a "mountain" or "foothill" carpenter bee.

Don't look now, but a garden spider almost grabbed a tiger by the tail. The tiger? That would be the Western tiger swallowtail, Papilio rutulus. The ragged wings of the butterfly (below) show signs of a close encounter with a predator--maybe another spider, a praying mantis or a bird.

The drama unfolds slowly. The crafty praying mantis that's perched atop a zinnia raises its spiked, grasping forelegs and silently waits for unsuspecting prey. A sweat bee cruises by. Then a second one. Then a third. They do not land and the praying mantis does not move.

Ah, the little intricacies of life... We were walking along a stretch of the coastal town of Bodega Bay when we spotted something we'd never seen before: a bubble on a syrphid fly. Syrphid flies, also known as hover flies or flower flies, are pollinators, just like honey bees.
