Flies Are Pollinators, Too!

Syrphids Back Again

Have you seen the little syrphid flies, aka flower flies and hover flies, hovering around the early spring blossoms? We saw half a dozen of them Monday, Feb. 15 nectaring a white ceanothus at the Marshall Post Office in Marin County. The ceanothus is a...

Hovering

The warmth of the sun and the lure of nectar beckoned the hover flies or flower flies to our bee friendly garden.We saw this one nectaring the rock purslane (Calandrinia grandiflora) last weekend. Native pollinator specialist Robbin Thorp, emeritus...

If It Looks Like a Duck....

If it looks like a duck, quacks like a duck, and walks like a duck, it's probably a duck. If it looks like a bee, buzzes like a bee, and visits flowers like a bee, it might not be a bee. It could be a fly, or more specifically, a syrphid or flower...

Knobbed antennae

SYRPHID FLY has a specialized bristle or arista on the end of each antenna. It looks like a knob. In comparison, the honey bee has long antennae bent at a right angle. (Photo by Kathy Keatley Garvey)
