How a 'Bear' Can Outsmart a Fox
There's a way for a bear to outsmart a fox. A teddy bear bee, that is. We just witnessed a male Valley carpenter bee, Xylocopa sonorina, aka "the teddy bear bee," buzz up to a patch of foxgloves, Digitalis purpurea. Then he engaged in the foraging behavior...

In Praise of Bumble Bees
When was the last time you sighted a bumble bee? Photographed it? It's National Pollinator Week and one of our favorite bumble bees is the yellow-faced bumble bee, Bombus vosnesenskii. It was also a favorite of internationally renowned bee expert Robbin Thorp, distinguished emeritus professor of...

Under Attack: European Wool Carder Bee Vs. Male Valley Carpenter Bee
Meet the competitors. In this corner, meet Mr. Teddy Bear. He's a blond, green-eyed carpenter bee, Xylocopa varipuncta, a native, and one of three species of carpenter bees commonly found from northern to southern California to western New Mexico. In the other corner, meet Mr. Bodyslam....

Meet Mr. Bodyslam, a very territorial European wool carder bee. He patrols the foxgloves. (Photo by Kathy Keatley Garvey)
Mr. Bodyslam targets the unsuspecting Mr. Teddy Bear. "Hey, get away from my flowers and nobody gets hurt." (Photo by Kathy Keatley Garvey)
Mr. Bodyslam is moving so fast, he's a blur. (Photo by Kathy Keatley Garvey)
And the battle begins! Mr. Bodyslam attacks Mr. Teddy Bear. "Hey, can't a fellow get a bite to eat in peace?" (Photo by Kathy Keatley Garvey)
Gotcha! The attack turns vicious. Mr. Bodyslam slams into Mr. Teddy Bear, a blow that prompted Mr. Teddy Bear to depart (only to return). (Photo by Kathy Keatley Garvey)
Robbing the Nectar
It's the easy way to do it. A carpenter bee heads for a foxglove blossom and drills a hole in the corolla to sip the nectar. This is "nectar robbing"--bypassing the pollination process and heading straight for the reward, the nectar. Honey bees are quick learners. Soon they're sipping nectar from...
