They're definitely attracted to it.
Honey bees forage furiously on the California buckeye (Aesculus californica).
It's not a good bee plant, though. It's poisonous.
Of California's main bee-poisonous plants--buckeye, death camas (Zigadenus veneosus) corn lily (Veratrum californicam) and locoweed (Astragalus spp.)--the most hazardous to bees because of its wide distribution is the buckeye tree.
Its distribution includes the UC Davis campus. If you walk behind Hoagland Hall, you'll see a thriving buckeye.
And bees and other insects foraging on the blossoms.
"Symptoms of buckeye poisoning usually appear about a week after bees begin working the blossoms," according to the Cooperative Extension booklet, Beekeeping in California, published in 1987 by the UC Division of Agriculture and Natural Resources. "Many young larvae die, giving the brood pattern an irregular appearance. The queen's egg-laying rate decreases or stops, or she may lay only drone eggs; after a few weeks, an increasing number of eggs fail to hatch or a majority of young larvae die before they are three days old."
The booklet, co-authored by six bee experts--five from UC Davis--points out that "Some adults emerge with crippled wings or malformed legs and bodies."
"Foraging bees feeding on buckeye blossoms may have dark, shiny bodies and paralysislike symptoms. Affected colonies may be seriously weakened or may die."
UC Davis Extension apiculturist Eric Mussen edited the publication. Other co-authors were UC Davis entomology professors/apiculturists Norman Gary and Robbin Thorp (both now emeriti); apiculturist Harry H. Laidlaw Jr., UC Davis professor of entomology (deceased); and apiarist Lee Watkins (deceased). Also lending his expertise: Len Foote of the California Department of Food and Agriculture.
If the name Harry H. Laidlaw Jr. sounds familiar, that's because the bee facility on Bee Biology Road, about a mile west of the central campus, carries his name.

Mother's Day, insect-style, dawned like any other day. In our back yard, golden honey bees foraged in the lavender and those ever-so-tiny sweat bees visited the rock purslane.
The honey bees? Those gorgeous Italians.
The sweat bees? Genus Lasioglossum, as identified by native pollinator specialist Robbin Thorp, emeritus professor of entomology at UC Davis. He figures the female sweat bee (below) may be L. mellipes, which is brownish toward the tips of the hind legs.
A trip to Benicia yielded a photo of a ladybug chasing aphids. It was almost comical. A fat aphid appeared to be playing "King of the Hill" while other aphids sucked contentedly on plant juices, unaware of pending predators.
While the aphids wreaked havoc on a very stressed Escallonia (fast-growing hedge in the family Escalloniaceae), the ladybugs, aka lady beetles, wreaked havoc on some very stressed aphids.
After all, "stressed" spelled backwards is "desserts."

First the buds, then the blossoms, then the bees.
The Häagen-Dazs Honey Bee Haven, a half-acre, bee-friendly garden planted in the fall of 2009 next to the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, UC Davis, is, in one word—spectacular.
The strawberries planted in the haven are in various stages of growth: buds, blossoms, immature fruit and now ripe fruit.
The bees did it.
It's a good time to view the garden, which is open from dawn to dusk every day. There's no admission charge.
You'll see art work; assorted fruits, vegetables and herbs; ornamental plants; and insects! The garden provides the Laidlaw honey bees with a year-around food source, raises public awareness about the plight of honey bees, encourages visitors to plant bee-friendly gardens of their own, and serves as a research site.

Nero may have fiddled while Rome burned, but the honey bees just kept on working.
We recently visited an apiary in Glenn County, and the honey bees were all over the fiddlenecks in patches adjacent to the hives. A springtime scene of golden flowers and buzzing bees. An artist's dream...a photographer's delight...
The fiddleneck (genus Amsinckia) is kissing cousins with borage and forget-me-nots in the family Boraginacae. The flower-laden stems curl over like the head of a fiddle or violin in concert. And when a honey bee forages on the fiddleneck, the stems bend even more.
I think there's a country song there somewhere. It bends, but doesn't break. Tune in, tune out. It's livestock's poison but bee's nectar.
Fiddle de-dee (good!) for the bees...fiddle de-dum (bad!) for the livestock.

That old saying, "Be all you can be," should be changed to "Bee all you can bee."
Have you ever seen festooning in a bee hive, when the bees link their legs together to perform tasks?
"They festoon when they're producing a lot of wax and drawing new comb," said Extension apiculturist Eric Mussen of the UC Davis Department of Entomology faculty.
Sometimes bees will build comb in bee space, and when the beekeeper lifts out a frame and scraps away the excess comb with a hive tool, the bees may festoon.
Such was the case yesterday at the Harry H. Laidlaw Jr. Honey Bee Research Faciity at UC Davis.
If a chain is only as strong as its weakest link, does that apply to bees?
