What's That Bug? does not endorse extermination

Ed. Note: We have never made any of the Prionid Beetles a Bug of the Month, and summer is the season for the various species from coast to coast.  California has the California Prionus and the Eastern states have the Broad Necked Root Borer.  Many Prionids exhibit distinct sexual dimorphism, with the smaller males having more pronounced antennae.  Many females are practically or totally flightless, and males are attracted to lights at night.  Here is a recent letter.

I don’t think I’ve seen a bug this big in New York before. It’s slowly walking around my sidewalk and sticking its butt up in the air like this, with a yellow thing that is protruding and retracting.

Broad-Necked Root Borer

Hi J,
Your insect is a female Broad-Necked Root Borer,
Prionus laticollis, and the yellow thing is her ovipositor which is used to lay eggs.  According to BugGuide:  “Eggs are inserted into ground (or under litter) in groups. Larvae tunnel downward to feed on living roots of a variety of trees and shrubs. At first they may feed on bark, but then proceed to hollow out small roots.”

Le Longicorne des Champs

Hi Kelly,
In French speaking Canada, this pretty Longhorned Borer Beetle is called Le Longicorne des champs, but alas in the U.S. it has no common name.  It is known scientifically as
Clytus ruricola, though it might also be a closely related species.  You can see BugGuide for additional information like that the “Larvae feed on decaying hardwoods, especially Maple Acer species.

Bugs in basement
Location: Cinicinnati, OH

Hello,
I have seen several of these bugs crawling around in my basement. Although I thought I saw wings on them, I never see them fly. I thought I saw pincers on their head, but don’t see one in this picture. Could that be a pincer on it’s bottom? I am curious to know what this bug is and if it’s harmful or dangerous. Seems to have yellow colored stripes. At first I thought I was looking at some sort of bee, but it is just crawling around and not behaving like one!

I just submitted a picture to the site. I will attach it again. After some reading online, I think it might be a Embioptera. What do you think?

Hairy Rove Beetle

Dear DN,
This is a Rove Beetle in the family Staphylinidae, and we believe it is a Hairy Rove Beetle,
Creophilus maxillosus, which we matched to images on BugGuide.  There is no way we can bring this up delicately, so we will just quote BugGuide which indicates Hairy Rove Beetles feed  “on carrion and dung.”  We suggest that you look in your basement for potential food sources.

Thank you.
that makes sense. We recently had a dead mouse, that then caused a fly infestation that finally has gone away. but i am sure we have a few dead maggots hiding in the basement!

Stink Bug we believe

Hi Giovanni,
Sorry we missed your original email, but we are not physically able to respond to all of the mail we receive.  Thanks for resending the image.  We believe this is a Stink Bug in the family Pentatomidae, but we don’t know the species.

4.5” Long flying bug with large pincers
Location: Enola, PA

I found this beauty on my shed door after mowing my yard on June 25th. I’m in central PA. I’ve lived here 11 years and I’ve never seen anything quite like it. I got very close to it and it kept turning it’s head to look at me when I was photographing it, but never attempted to flee or bite.

Male Dobsonfly

Dear Gary,
We knew what insect you wanted identified by your subject line before even viewing the photos.  Dobsonflies are one of our most frequently asked summer identification requests.  This beauty is a male who may be distinguished by the mandibles.  We wonder what injury resulted in the broken right mandible.

Head of a Prionid Beetle

Dear Kerri,
We feel like we have been involved in a Sherlock Holmes novel or a CSI episode.  This is the head of a Prionid Beetle, and there are numerous species that might be encountered in New Hampshire.  Our most likely subject is a male Broad Necked Root Borer,
Prionus laticollis, which is pictured in our archives and on BugGuide where it is indicated that:  “Antennae have 12-13 segments.”  The head you found appears to have 12 segments on the antennae.  The big question is how did that head get on your desk.  We don’t know where your desk is, and that might help.  Birds will sometimes eat fatty insects, and the body of a Prionid Borer is full of fat, and the head hasn’t much nutritional value, not to mention it is harder and less palatable.  We doubt that your desk was outdoors under a tree where a bird might drop the head of a Prionid it was eating, so we will eliminate a bird.  BugGuide also indicates:  “Males are attracted to lights.”  This is a male as females have much less developed antennae.  If this Prionid was attracted to a light and your house cat encountered it, perhaps the cat ate the body of the insect and left you the head as a trophy.  The predator will have to remain a mystery.
