The queen bee (the largest bee, center) is surrounded by her court, the worker bees, who take care of her every need. They feed her, groom her and protect her "and then they have the additional tasks of rearing and feeding her young," said bee breeder-geneticist Susan Cobey of the UC Davis Department of Entomology.

The Queen Bee

September 11, 2008

If you were a queen bee, you'd be laying about 1500 to 2000 eggs today. It's your busy season. "She's an egg-laying machine," said bee breeder-geneticist Susan Cobey of the Harry H. Laidlaw Jr. Honey Bee Research Facility at UC Davis. "And she's the mother of all the bees in the hive.

Build It And They Will Come

Build it and they will come. Baseball's Field of Dreams? No, a bee nesting block. Think "bee condo." It's an artificial nesting site made of wood and drilled with different-sized holes and depths to accommodate the diversity of native pollinators. Often the bee block is nailed to a fence post.

I've Been Robbed!

September 5, 2008

Robber at work. No, this isn't a bank heist or a gas station hold-up or a home invasion. A carpenter bee is slitting the sides of salvia (sage) to steal the nectar. Floral larceny! Book 'em, Danno! Carpenter bees are nectar robbers.

Mighty Mite

September 4, 2008
By Kathy Keatley Garvey
It's a mighty mite and it's causing beekeepers fits. The varroa mite (see photo below) is an external parasite that attacks honey bees. It sucks blood from the adults (apparently preferring drones, the male bees) and from the brood (immature bees).

Honey, Meet Me at the Fair

Good Bug, Bad Weed

Hillary Thomas' biological control research on a leaf-eating beetle that targets saltcedar has scored a bullseye. Thomas, a doctoral candidate in entomology at UC Davis, has received a $15,000 Robert and Peggy van den Bosch Memorial Scholarship to support her research.

Carrying a Lot of 'Baggage'

If she were boarding an airline, she'd be charged double for baggage. But she didn't and she wasn't. She's a pollen-packed sunflower bee enjoying our sunflower. Not a honey bee but a sunflower bee. A native bee.

If I Were a Carpenter...Bee

August 14, 2008
By Kathy Keatley Garvey
I've got black bumblebees buzzing around our backyard like crazy, the caller said. They're loud. Very loud. They're dive-bombing and scaring the cat and dog. I've never seen anything like this before. The unwelcome visitors were not bumblebees. They were carpenter bees.
