He's the bully in the bee garden.
If you've ever watched the male European wool carder bee (Anthidium manicatum) patrolling "his" flower patch, you'll see him targeting insects several times larger than he is.
Take the case of the Valley carpenter bee (Xylocopa varipuncta), one of the largest bees in California. The female is solid black, while the male is a green-eyed blond.
Last week we were watching female Valley carpenter bees trying to gather some nectar from a bluebeard (Caryopteris x clandonensis) when the much smaller male carder bee dive-bombed her.
The male was also dive-bombing and body-slamming honey bees, sweat bees leafcuter bees and other bees, in addition to butterflies. They do that to "save" the flowers for their own species and perchance to mate!
As the sun set, the sleepy male carder bees headed over to a bee condo to grab some shuteye.
The bee condo was meant for nesting blue orchard bees (which pollinate the almonds in the spring).
Bee condos can also be occupied by other critters, including spiders, wasps and European wool carder bees!

Birds do it...bees do it...
You've probably seen the territorial male European carder bees on patrol. They dart through the stems of a nectar treasure, such as bluebeard (Caryopteris 'Blue Mist'), knocking off all floral visitors. They're trying to save the nectar for their girls, perchance to mate.
These boy carder bees are often called the "bullies of the bee world," as they whack-smack, bodyslam and dive-bomb unsuspecting honey bees, leafcutter bees, carpenter bees and other insects that are just trying to get a share of the nectar. (Davis insect photographer Allan Jones calls them "bonker bees.")
Sometimes you'll see the female wool carder bees nectaring, or carding fuzz from the plants for their nest. Sometimes you'll see a male carder bee pause from patrolling to take a a nectar break. It's like filling up the tank.
And sometimes, if you get lucky, you'll see two bees becoming one.
