Every insect looks prettier when it lands on a tower of jewels (Echiium wildpretti).
When in full bloom, the 9-to-10-foot-high plant, native to the Canary Islands, blazes with firecracker-red flowers. It's a showstopper.
Syrphid flies, aka flower flies or hover flies, battle with honey bees to sip the sweet nectar.
The flower flies flit in and out of the blossoms, barely visible.
However, these insects suffer from an identity crisis. Their wasp-like coloring wards off predators. That same coloring confuses people, too. The average person on the street--or in a flower bed--thinks they're bees.
They're not. They're flies.
UC Davis-trained entomologist Robert Bugg wrote an excellent pamphlet on flower flies that's downloadable free from the UC Division of Agriculture and Natural Resources. Titled Flower Flies (Syrphidae) and Other Biological Control Agents (Publication 8285, May 2008), it will help you identity flower flies.
Not bees. Not wasps. Flies.
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.
Caught on the cosmos.
Syrphid on Cosmos
That's what it takes to capture images of syrphids, aka flower or hover flies.
They are oh, so tiny and they move oh, so quickly. As the morning dawns, you wait, camera poised, near their preferred blossoms. You'll need a keen eye and a quick trigger finger--not to mention a good macro lens and a high shutter speed to freeze a moment in time and space.
If you're stealthy and don't startle or shadow them, you can observe them nectaring just inches away from you. This is big game hunting, but with little insects.
And, another frozen moment in time and space.
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.
