A brilliant sunflower clinging to the red ring of autumn.
And here comes a common sunflower bee, Melissodes agilis (this is a female, as identified by native pollinator specialist Robbin Thorp, emeritus professor of entomology at the University of California, Davis.)
The sunflower bee is a specialist on sunflowers (Helianthus spp.). Scientists know this as a long-horned ground-nesting bee, a member of Anthophoridae. Both the plant and the bee are native to the United States.
Melissodes agilis is commercially important. And it's common.
But there's nothing "common" about it when "sunflower bee" meets "sunflower."
The beauty is overwhelming.

What's better than a bee threading through a flowering artichoke? Two bees, a honey bee and a long-horned sunflower bee.
Flowering 'chokes are big draws for bees. Plant 'em, let 'em flower, and they will come. Sometimes in droves. Sometimes in diversity. Always amazing.

An Italian honey bee, Apis mellifera, buzzing low and packing white pollen, ignored us.
From their missions they did not stray.

Makes sense that the sunflower bee (Svastra spp.) forages on the genus Cosmos.
Cosmos (also the common name) is a member of the sunflower family, Asteraceae.
Sunflower bee: sunflower family. A specialist bee.
On a recent trip to the Luther Burbank Home and Gardens in Santa Rosa, we spotted scores of sunflower bees on cosmos, each bee packing a heavy load of golden pollen.
There was a pollen party going on, pure and simple.
Although the sunflower bee, as a floral visitor, is often mistaken for a honey bee, there's no mistaking that this is a pollinator, too.

Will the real honey bee stand up?
Not all bees are honey bees and not all floral visitors that look like bees are bees. Sometimes they're flies.
A recent trip to the Häagen-Dazs Honey Bee Haven, a half-acre bee friendly garden located next to the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road at the University of California, Davis yielded a variety of floral visitors.
They all took a'liking to the 8-foot-tall Mexican sunflower (Tithonia rotundifolia), as orange as a Halloween pumpkin.
The floral visitors?
One was a drone fly (Ristalis tenax).
One was a sunflower bee (Svastra obliqua expurgata).
And one was a honey bee (Apis mellifera).
Scores of editors have mistaken drone flies and sunflower bees for honey bees and published photos that make entomologists cringe.
Entomologist/insect photographer Alex Wild of the University of Illinois (he received his doctorate in entomology at UC Davis with major professor Phil Ward), wrote an eye-opening piece on his Scientific American blog about mistaken insect identities. You'll want to read this--and then take a look at his amazing Myrmecos site.
And if you want to learn about insect photography from a master, be sure to attend his seminar from 12:10 to 1 p.m., Wednesday, Oct. 26 in 122 Briggs Hall, UC Davis. His topic: "How to Take Better Insect Photographs."
And maybe he'll mention that Bees of the World book cover. The image is a fly.

Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road at the University of California, Davis, is more than just a haven for honey bees.
Think bumble bees, carpenter bees, leafcutter bees, sweat bees, sunflower bees and scores of other bees.
The grand opening celebration of the garden will take place from 10 a.m. to 2 p.m. on Saturday, Sept. 11, but the bees and other native pollinators are already out there.
And have been for some time.
Native pollinator specialist Robbin Thorp, emeritus professor of entomology at UC Davis, has been monitoring the garden for the past two years--from open field to planted garden.
He's found more than 50 different species of bees representing five families (Andrenidae, Apidae, Colletidae, Halictidae and Megachilidae).
They include the striped sweat bee Halictus ligatus from the family, Halictidae; the yellow-faced bumble bee, Bombus vosnesenskii from the family Apidae; the leafcutter bee, Megachile sp., from the family Megachilidae; and the sunflower bee, Svastra obliqua expurgata from the family Apidae.
How colorful they are. And how diverse.
