Hello, Bugman! Maybe you could tell me what bug this is? It’s very large (see penny in photo for scale)
It doesn’t appear to be a cockroach due the the antennae, so I’m stumped.

Dear Buggily Yours,

Male California Prionus

Male California Prionus

Dear Courtney,
Though is it named for the Golden State,  the range of the California Root Borer,
Prionus californicus, extends well beyond California as you can see from the sighting data on BugGuide.  According to BugGuide:  “Larva feed primarily on living deciduous trees (oaks, madrone, cottonwood) and are also recorded from roots of vines, grasses, and decomposing hardwoods and conifers. Will also attack fruit trees growing on light, well-drained soils (e.g. apple, cherry, peach).”  This individual is a male which can be distinguished from the female by his developed, distinctly sawlike antennae.

Hi Man of Bugs,
I am from Oklahoma and it is super hot out here right now. I found this guy coolin’ down in the climate control units at Aspen Mini Storage. I believe it’s a Cottonwood Borer but I thought he was a beaut and had to show you!
Thank you!

Hi Sommer,
You are correct that this is a Cottonwood Borer, and it is an impressive and unforgettable beetle.

This bug was hiding in the sunroom INSIDE the house, cornered by the cat. The bug was aggressive and actually squeaked when confronted. Very large, two inch range. Sorry, the dead body is gone. But, we have a picture. Looking forward to any guesses. Thanks, Keith

Brown Prionid

Hi Keith,
This impressive beetle is a Brown Prionid,
Orthosoma brunneum, and while we tend to get a few submissions of Brown Prionids each summer, we have had a significantly greater numer this summer.  The larvae are wood borers and according to BugGuide:  “Breeds in poles, roots(?) in contact with wet ground.”  We suspect this individual was attracted to your house because of lights.

I know this is a Cottonwood Beetle, found at the Riverways Migratory Bird Sanctuary in West Alton, Missouri on August 5, 2014. I’ve never seen one of these before and they are impressive looking.

Cottonwood Borer

Dear Cara,
Your image is positively gorgeous.  We generally crop images so that the “bug” is featured nicely for the web, and the same is true of your image, but we are also posting your entire image so that our readers can appreciate the loveliness of this Cottonwood Borer within the landscape, and we hope folks know that clicking on the images on our site in postings after 2009 will bring up an enlarged view in a new screen.  While Cottonwood Borers are not the largest Longicorns in North America, and we can think of a few that are prettier than the Cottonwood Borer, it is probably the prettiest, really large Longicorn, and we fully agree with you that it is an impressive site.

Found this big in the kitchen, kind of pretty and quite large, but I wasn’t sure what it is.
