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...

Squatters' Rights

Fly-In

Squatters' rights. A dandelion poking through the rocks near Nick's Cove on Tomales Bay, in Marshall, Sonoma County, seemed an unlikely host for squatters' rights. It first drew a tiny bee, barely a quarter-inch long. It was a female sweat bee, family...

To Sir (Syrphid), With Love

Syrphid larva

If you see a caterpillar near a cluster of aphids, don't squash it. It could very well be the larva of a syrphid or hover fly (family Syrphidae) and it's eating aphids. What do they look like? I happened to capture an image of a  tiny syrphid...

The Meeting

Spotted cucumber beetle

Last Saturday the rock purslane in our bee friendly garden drew a honey bee, several hover flies and one spotted cucumber beetle. A hover fly landed on a blossom, only to find a spotted cucumber beetle there first.

Let It Rain

Hover fly on sage

Ah, rain! Ah, liquid precipitation! Just when we were feeling drought-stressed, the weather forecast turned to rain. I don't know if "the rain in Spain falls mainly on the plain," but the rain in Northern California fell squarely on our bee...
