Subject: Huge Beetle Found! Invasive or Not?
Location: Eastern United States, DE

Hello! I’ve got a bug on my hands – well, in a jar – and I don’t know what to do with it.
I have lived in this area for 20+ years and am an avid outdoorswoman. This critter was trying to get into my house through the window screen, and I’d like some expert help figuring out just what it is. Because I’ve never, ever seen it before.
This beetle is large, nearly two inches long, with a slender body about half an inch wide. It’s a rusty reddish brown color, with black mandibles and antennae about an inch long. There are no discernible markings.
I’ve confirmed that it is not a cockroach of any variety, and if it didn’t have terrifying looking mandibles I’d be picking it up to take better photos.
I’d like to know if it’s a type of boring beetle or not, so I can know if it’s invasive or not. I’ve never seen it before and it’s rather concerning to see something this…enormous on my window trying to nibble the screen.
Any info pointing me in the right direction would be awesome. :)

Brown Prionid

Brown Prionid

Dear Kat of the Coast,
Root Borers in the family Prioninae are quite impressive beetles and there are several native species found in Delaware, even if they have managed to avoid detection by you in the past.  This is a Brown Prionid,
Orthosoma brunneum, and you are wise to avoid its mandibles.  The grubs of Root Borers live feeding on wood for several years and the mandibles of the adults need to be strong enough to chew their way to the surface once metamorphosis is complete.  We suspect this individual was attracted to light, and that is why you discovered it on your screen.  See BugGuide for additional information on the Brown Prionid.  We would urge you to release your captive Brown Prionid.

Hello!
I found this guy on a dry rock in a small stream in the far northern Sierra Nevada mountain range. One of my friends said it looked like a “cross between a bee and a long horned beetle.” then he quipped that was not possible. I was surprised as he is hard to stump!

Lion Beetle

Lion Beetle

Dear S. Dykstra,
When we first received some excellent images of a Lion Beetle,
Ulochaetes leoninus, in 2009, we were quite confused and amazed ourselves.  BugGuide now has many more images of this unusual Cerambycid, but there is still no information posted on the Info page.  According to the Introduction to California Beetles by Arthur V. Evans & James N. Hogue:  “The Lion Beetle … looks and behaves just like a bumblebee, even attempting to sting with its ovipositor.  When disturbed, the Lion Beetle raises its abdomen forward over its back while flapping its wings, reinforcing its bee-like appearance.”

Hello, we were intrigued by this bug spotted on our cedar tree. We wondered what it might be. It’s about an inch long, it’s a dull olive green and has four faint black spots.
We think it’s a beetle because of the elytra?
Cheers and thank you!

Dear Snowpea,
This is a Longhorned Borer Beetle or Longicorn in the family Cerambycidae.  We will attempt to determine a species for you.

Hi, Daniel:
Sure, this is a “Linden Borer,” Saperda vestita.  Nice beetle!

Subject: Ash borer?

Hi bugmen and bugwomen,
I took this photo of an insect sunning itself on the side of my house. I searched your files and online.
the closest I could narrow the ID was to the BANDED ASH BORER beetle, but all the photos I found lacked yellow stripes across the thorax. Otherwise, it seems to be a close match.
is this a banded ash borer, or perhaps a relative?
We have been losing trees in the Chicagoland (IL) area at an alarming pace. (mostly elms and ash), and work crews were in my neighborhood felling diseased trees last week.
My guess is this bug is in the process or relocating to new food source.
Many thanks for all you do.

Neoclytus scutellaris

Neoclytus scutellaris

Dear Jill,
You are quite astute to observe the similarities between your insect and the Banded Ash Borer,
Neoclytus caprea, since they are in the same genus.  According to BugGuide, there are 25 members in the genus Neoclytus in North America, and many look quite similar, probably requiring the actual examination of the specimen by an expert in the family Cerambycidae to determine the actual identity.  Based on the striping pattern on the thorax and head, we believe your individual is Neoclytus scutellaris, based on its similarity to this individual posted to BugGuide.  The species has no common name, and according to BugGuide:  “Larvae feed in sapwood of (dead?) oaks, hickories, also grape.”  It is also worth noting that adults do not feed on wood, and they are most commonly found taking nectar from flowers, sap, fruit and other sweet substances.

Thank you for your response and reassurance! (I’m so glad this bug didn’t go on to feast on my elm tree). We have lots of native berry trees in our yard, and the bug was near our cherry tree when the photo was taken. Your description of it’s feeding habits makes sense.
Thanks, Jill

I found this beetle early one morning. I thought it was a root beetle but the antennea were diffrent. It was bigger than my thumb and had wings. I collected it and put it in a glass bowl with a wet papertowel as I had to leave town for a couple of days. My wife was scared of it and had to let it go before I could take more pictures of it.

Ponderous Borer

Hi Steve,
Your image is not very sharp, but this appears to be a Ponderous Borer,
Trichocnemis spiculatus, a member of the subfamily Prioninae that includes the Root Borers.  See BugGuide for additional images of the Ponderous Borer.

Hi!
So the other night (low 80 degree night, pretty humid, on July 14th) I was sleeping in my basement when I woke up to an insect crawling over my face and on my body. I proceeded to jump out of bed, scream and run to my couch (I’m not a huge bug fan) about 30 seconds later the bug crawled across the bed and took flight (clumsy flight) towards a different part of the room. We’ve been living in Westchester, NY (about 17 miles north of new york city) for over 17 years and have never seen a cockroach, our basement is pretty dry as far as basements go and we keep it pretty clean, however, there are a number of american cockroaches in my local middle and high school. When inspecting the bug after we had caught it a day later I noticed its antennae did not match the american cockroach. Is this a beetle? Or possibly another species of bug? I’m extremely curious and confused, any information would be greatly appreciated.

Brown Prionid

Dear Clara,
This impressive beetle is a Brown Prionid.  Though they are not considered dangerous, they have strong mandibles that may give a painful bite, possibly even drawing blood, if they are carelessly handled.
