Burrowing Bug

Dear Debbie,
We empathize with your health crisis.  We are confident that this is a Burrowing Bug in the family Cydnidae, possibly from the genus
Dallasiellus like this Southern California individual pictured on BugGuide.  We cannot locate any information on BugGuide regarding their tendency to bite, nor can we find information elsewhere in our quick search.  Hopefully, now that you have an identification, you might be able to locate helpful information on your reaction.


Subject:  Is this a bed bug? Kinda looks like one.
Geographic location of the bug:  Clinton township, Michigan

Been getting bug bites once in awhile not sure if they are mosquito bites, because it’s only one at a time. Thinking the worst bed bugs. I haven’t been sleeping in the bed, my husband never gets bit.  But I found out mosquitos only go for my type of blood, maybe bed bugs do to? Anyways found this bug on my bed today he’s a 1/4 inch big, thought bed bugs were smaller? And the legs don’t look like they are all in the front like a bed bug. Can you help me?

Black Ground Bug

Dear Sue,
This is NOT a Bed Bug, but it is a True Bug in the same suborder, Heteroptera, as Bed Bugs.  We believe this is a Black Ground Bug,
Microporus nigrita, which we found on BugGuide.  According to BugGuide:  “native to, and widespread all across the temperate and southern Palaearctic, adventive in NA.”

We have discovered a few of these over the last couple days on our tile floor. I had carpet beetles in a previous home, it doesn’t look like that. Any advice would be great, thank you!

Immature Burrowing Bug

Dear Mark,
At first we thought this was a Cockroach nymph, but upon lightening your image, we realized we were looking at a True Bug nymph.  We are relatively confident we have identified it as an immature Burrowing Bug in the family Cydnidae thanks to this BugGuide image.  According to BugGuide:  “body usually ovoid, heavily sclerotized, dark, legs often spiny” and  “take liquid from the phloem vessels, unlike other heteropterans and often feed on roots.”  The real mystery for us concerns why the are in you home.  Is your tile floor in a basement?  Was there any recent excavation nearby?  We are confident they will not harm your home and that they are accidental intruders rather than infesting species.

Subject: Different species of bugs aggregated?
Location: Rome, Italy
October 23, 2015 11:56 am
my dad found this aggregation of bugs in Rome and took a picture. He then sent it to me since I am studying zoology and I started doing some researches about it. By reading your website, I found out that the situation we are looking at is immature bugs, forming aggregation. However that post was about Harlequine bugs, individually coloured of both colours black and red. While in my picture some bugs are red with black stains, while other, in the same aggregation, are entirely black.
Therefore I was wondering, are they different species? Or maybe black ones are younger and still did not develop the red colouration?
Hope you can give me some answer 🙂
Thank you very much!

Ebony Bug Aggregation

Ebony Bug Aggregation

Dear Costanza,
We believe this is an aggregation of Ebony Bugs in the family Thyreocoridae, and that the red individuals are the immature ones.  British Bugs has images of one species.  Also pictured on British Bugs is the Burrowing Bug,
Canthophorus impressus, in the family Cydnidae.  Alas, there is not enough detail in your image to be certain.

HI. We saw this yesterday. They are mostly black but there are a few with red markings underneath. I couldn’t tell if they were preying on the red marked ones or if they were all feeding on the same thing.
I don’t often see such large groups of beetles, except on my cucumber plants!

Aggregation of White Margined Burrowing Bugs

Aggregation of White Margined Burrowing Bugs

Hi Jess,
Based on this image we located on BugGuide, we believe this is an aggregation of White Margined Burrowing Bugs,
Sehirus cinctus, but interestingly, there are only images of individuals on BugGuide.

Ebony Bug

Hi Hector,
Formerly known as a Negro Bug, the more politically correct Ebony Bug has become the more accepted common name for insects in the family Thyreocoridae.  They are also sometimes simply called Black Bugs.  According to BugGuide, they are:  “Shiny black, broad oval, convex shape. Tibiae have no spines or slender ones. Large scutellum covers most of abdomen and wings. Look like beetles but have 5-segmented antennae and 4-segmented beak.”  BugGuide also notes:  “Common on flowers and other vegetation” and they will not harmful to your home.

Correction:  July 24, 2017
Upon posting a new image of what we believe to be an immature Burrowing Bug, we are rethinking this old posting and we now believe, based on this BugGuide image, that this too is an immature Burrowing Bug.  The BugGuide  description is “body usually ovoid, heavily sclerotized, dark, legs often spiny.”
