Carpenter Bee (Xylocopa varipuncta) is California’s
largest bee and comes in two distinct colors. Males are a fuzzy gold color and
have been called “teddy bear” bees while females are shiny and black. Both are
excellent flower pollinators. They are named for their ability to burrow into
wood, preferring unpainted and unstained fence posts, telephone poles, tree
trunks, and similar types of natural timber. However, only the female Valley
Carpenter Bee does the excavating.
Valley Carpenter Bees tend to be the first to rise from hibernation in the
spring. It uses this extra time to prepare for the mating process by consuming
large amounts of floral nectar. Eventually, it becomes very territorial, marking
its territory by glandular secretion in order to ward off other males from
stealing potential mates.
Did you know? Male Valley Carpenter Bees are of little
threat to humans as they do not have stingers, while female Valley Carpenter
Bees do have one, but will only sting when provoked.
