This guy has been hanging around our house for several days. He has no friends and just seems interested in our house. He is not aggressive and has quite a loud buzz!

Carpenter Bee

Dear Susan,
This is a solitary Carpenter Bee, and it is a female.  Female Carpenter Bees live a relatively long time because it is labor intense for them to excavate and provision a nest.

Thank you Daniel for your prompt reply.  Should we be concerned that she may try to be nesting in our home?

According to Charles Hogue in Insects of the Los Angeles Basin:  “Carpenter bees are so named because they bore into wood, forming tunnel-like nests for the rearing of the young.  Many kinds of wood are used:  although fence posts, building timbers, and telephone poles often are attacked, the effects are seldom damaging.”

I found this on my porch in Palm Desert, California earlier today. I have seen hundreds of horseflies and this was much much bigger and the legs are thicker. It’s not a roach. Almost looks like a cross between a horsefly and a cockroach ! Any idea???

Female Valley Carpenter Bee

Female Valley Carpenter Bee

Dear Aimee,
This is a female Carpenter Bee in the genus
Xylocopa, most likely a Valley Carpenter Bee, Xylocopa varipuncta.  Interestingly, another member of the genus with clearer wings and a striped abdomen, Xylocopa tabaniformis, is known as the Horsefly-like Carpenter Bee, but according to BugGuide, it is only reported from Texas.  The Valley Carpenter Bee is a species with pronounced sexual dimorphism, meaning males and females are very different in appearance.  Females are black and males are golden.  We we in the garden at dusk last night and heard a loud buzzing.  We saw our first male Valley Carpenter Bee of the year.  Males are short lived and seem to appear only in spring.  Females that need to tunnel a nest in dead wood and then provision the nest with pollen for the larvae have a much longer life span.

Thank you!!! About 15 people told me it was a horsefly and I knew it wasn’t! Yay I win! Thanks to you!! I appreciate it!

Male Valley Carpenter Bee

Dear Nancy,
Thanks for sending three images.  That gives us a choice of what to post.  We are posting the close-up of this male Valley Carpenter Bee.  The species has pronounced sexual dimorphism, and the golden males look like an entirely different species than the black female Valley Carpenter Bee.  The differences are most stunning when the sexes are viewed together, and if there is still any doubt that they are the same species, here is a mating pair of Valley Carpenter Bees.

This bee-like bug came into our home in the early afternoon. We have orchards behind our home. He was fairly calm…not the typical frenetic bee like flying, but he had a very loud buzz. He seemed to hug the surfaces he landed upon and was attracted to light.

Male Valley Carpenter Bee

Dear Mommy Susie,
This is a harmless male Valley Carpenter Bee.  This is a species with extreme sexual dimorphism.  Males are golden and females are black, so the sexes appear like different species.  Females rarely sting and males are incapable of stinging.

Hi bugman!
I’ve found this female bee buzzing around my fluorescent tube light in early morning.
two of them were buzzing above a nearby dates palm tree, maybe they were examining the tree to make a nest or something.
sorry for the bad quality photos, I got the bee inside a plastic bag just to take a photo then released the little guy-gal- back outside.
can I get a more specified classification?
thank you for your works.

Carpenter Bee

Dear M.A,
We agree that this looks like a Carpenter Bee, and based on images posted to Science Open, we believe it is a male
Xylocopa (Koptortosoma) aestuans (Linnaeus).  Science Open states:  “Male covered by dense yellow pubescence” and your second image indicates a yellow abdomen.  The Wiki Spaces site has an image supports that identification.
