Unknown Rove Beetle

Dear Jacquie,
This is not a Cockroach.  It is a beneficial, predatory Rove Beetle in the family Staphylinidae, but alas, we have not had much luck determining a species name.  There are many species of Rove Beetles illustrated on NatureSpot, but none that looks quite like yours.  According to Mark Telfer’s Website:  “There are about 1,134 species in this family, as delimited in the Duff (2012) checklist. This one family thus contains over a quarter of the 4,072 species of beetle.”   We believe those statistics refer to the British Islands.

I need help identifying this bug. Found in Richmond Virginia on 2/12/17 on a warm afternoon. Usually I can find the bug through the internet, but not this time.

Brown and Gold Rove Beetle

Dear Phil,
You really didn’t need much help.  Most people don’t even recognize Rove Beetles as Beetles.  We believe this is either a Gold and Brown Rove Beetle,
Ontholestes cingulatus, or a closely related species.  We really like the Ozark Bill A Thousand Acres of Silphiums page.

Subject: Strange bug from Portugal

Hi, bugman.
Found this strange bug hanging around my backyard in Portugal, never seen one before. My cat chased it into the house. It’s nearing the end of winter now.
I’m of course wondering what it is. When the cat was trying to swat it around, I noticed it attempts to raise its tail like a scorpion and secretes a white liquid from the tip. A stinger of sorts, I presume?
The bug was of course released without harm.
Anyway thanks in advance for any help!

Devil’s Coach Horse

Dear David,
This native predatory Rove Beetle in the genus
Ocypus is commonly called a Devil’s Coach Horse.  They are not dangerous to humans, though they are able to expel a foul smelling odor from glands at the tip of the abdomen which they do while striking a curious curved posture that many folks liken to the appearance of a stinging scorpion.  This European native has naturalized in parts of North America and according to BugGuide:  “They often eat, and may help to control, the introduced brown garden snail.”

Hey Bugman,
On a recent trip to Borneo we came across this funky bug.
Very praying mantis in its stance, but flies like some sort of wasp.
Super cool creature that we spent about 30mins watching as it waited for ants or flys to cross its path so it could have lunch.
Thanks!

Rove Beetle

Dear Emily,
The front legs on your insects are quite unusual, and they do not seem adapted for walking.  Nonetheless, we are relatively certain that this is a Rove Beetle in the family Staphylinidae.  But for the front legs, your individual looks like this individual from Malaysia pictured on Project Noah.  This unidentified Rove Beetle from Paul Bertner’s Rainforest Photography site and the one from Borneo Bootcamp have similarly structured legs.  Because we will be away from the office for the holidays, we are postdating your submission to go live at the end of the month while we are away.

Subject: Earwig no forceps
Location: Logan Canyon, Utah

I found an unfamiliar bug that resembles an earwig. Although it looked similar, it was missing the forceps located near the rear of the insect. I extracted the DNA to see if I could use sequencing data to figure out what the insect was. My results came back as an isopod which made no sense (a pillbug). I am still trying to figure out what this bug is or the order it might belong in. If you have any advice I would appreciate it.

Rove Beetle

Dear Linsee,
This is a Rove Beetle in the family Staphylinidae which is very well represented on BugGuide, but alas, there is not enough detail in your image to determine an exact species identification.  We are quite curious about the DNA testing you conducted.  Was it part of a educational program?  We fondly remember our own Fruit Fly data from a high school genetics class experiment that was so very wrong.  If your results were part of a student experiment, the error makes much more sense than if funds were expended through a for profit company.

Thank You! That helps me out a ton and gives me another place to keep researching. We conducted the DNA test for my Genetics lab course. I am currently an undergraduate at Utah State University. We used the Roche High Pure DNA Extraction kit and we amplified the 648bp region in mitochondrial cytochrome-c oxidase subunit 1 gene using the Promega PCR with GoTaq amplification kit. I was wondering if region of mitochondrial DNA that we amplifed are to conserved between different orders of insects. Could that be a possibility?
Thanks Again!

Hi again Linsee,
Thanks for the DNA clarification.  Alas, our editorial staff does not have the necessary science background to answer your questions regarding shared DNA among the lower beasts.
