Butterflies, honey bees and hover flies can't get enough of red buckwheat.
Tight clusters of pink blossoms, coupled with gray-green foliage, grace red buckwheat (Eriogonum grande rubescens), a California native.
It's good for the insects and good for the gardener. It's drought-tolerant.
We planted red buckwheat in our bee friendly yard several weeks ago, and among the first to find it were hover flies, aka flower flies.
Hover flies (family Syrphidae) hover over flowers like a sightseeing helicopter. Then they dip down and sip the nectar.
They're often mistaken for honey bees. Many an editor has published a photo of a "honey bee" that was in reality, a hover fly.
California buckwheat is one of the attractions in the newly planted Häagen-Dazs Honey Bee Haven, a half-acre bee friendly garden next to the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, UC Davis. It is serving as a year-around food source for bees and an educational opportunity for humans. A public celebration will take place next June.
Look for the buckwheat!
Looking for Nectar
Cosmos flowers are somewhat like Libras. They balance.
In fact, the word, "cosmos," means "harmony" or "ordered universe" in Greek.
Plant cosmos and you'll soon be enjoying colorful flowers that belong to the Asteraceae family, which also includes sunflowers, daisies and asters. Plant a variety of colors--white, pink, orange, yellow and scarlet--and you'll see why the Spanish missions in Mexico favored cosmos.
They're beautiful and easy to grow.
An added benefit: they attract syrphids, also known as flower flies and hover flies.
Plant cosmos. Attract syrphids. Capture an image of a syrphid on a cosmos.

It's often mistaken for a honey bee.
It's not a honey bee. It's a hover fly or flower fly.
And this one, hovering around the plants last Saturday in the Storer Gardens at the University of California, Davis, looked like a Syrphus opinator to me.
So I asked UC Davis entomologist Robert "Bob" Bugg, who specializes in flower flies (Syrphidae), what it is.
"If I have to be an opinator, I'd opine that you're right," he quipped.
Bugg, who received his doctorate in entomology at UC Davis, does research on the biological control of insect pests, cover crops, and restoration ecology.
If you want to learn more about flower flies, read Dr. Bugg's "Flower Flies (Syrphidae) and Other Biological Control Agents for Aphids in Vegetable Crops" (Publication 8285, May 2008, University of California, Division of Agriculture and Natural Resources.)

It's commonly known as a hover fly, drone fly, flower fly, syrphid fly or "syrphid," says Robbin Thorp, emeritus professor of entomology at UC Davis who researches native pollinators from his headquarters in the Harry H. Laidlaw Jr. Honey Bee Research Facility on
"These are good honey-bee mimics," he said, "but note the short stubby antennae and bulging face." Also note the large eyes! (Reminiscent of the eyes of the male honey bee, the drone).
The hover fly moves like a helicopter, holding perfectly still for a moment or two, and then darting upward, downward and backward in flight.
Unlike bees and wasps, syrphids have two wings, not four. Also a syrphid-notable: black and yellow stripes on their abdomen. The coloring helps fool would-be predators.
In their larval stages, syrphids dine on plant-sucking pests like tasty aphids, thrips, mealybugs and scales, or munch on decaying matter in the soil or in ponds and streams.
They're the good guys. And girls.
These beneficial insects are like the ladybird beetles (aka ladybugs) and lacewings of the garden. In their larval stages, they prey on pests, and in their adult stages, they pollinate flowers.
Prey 'n pollinate, that's what they do best.
