So far I've only occasionally noticed carpenter bees in the garden.
This is the first carpenter bee I've observed on a Butterfly Bush Buddleja.
It is about 1 inch long and appears to be a California Carpenter Bee female Xylocopa californica.
Look at those huge eyes!
The bee spent a long time, maybe five minutes, on this one flower head, carefully collecting nectar from every flower.
The reflection in the bee's compact eyes is very interesting.
