What is this thing?
Location: Northern Colorado
October 30, 2011 11:29 am
Last week cleaning out underneath our kids bed we found this bug. My wife threw it outside in the snow and it died pretty quick. Then she took pictures. I looked it up on the internet and the only match I found was a Hissing Madagascar Cockroach. Here is my issue. We have never had one as a pet and have lived in this house for 7 years. The people before us have lived here for 30 years. Our friend saw this bug 2 weeks earlier, other than that we haven’t seen anything like this. How did it get into our house and is it what I found on the internet?

Cockroach

Dear Freaked Out In Colorado,
We agree that this is a Cockroach, and we cannot immediately disregard that it is a Madagascar Hissing Cockroach.  We believe it may be a Brown Hooded Cockroach or Wingless Wood Roach,
Cryptocercus punctulatus, but we are waiting to confirm that identification with Eric Eaton.  The Brown Hooded Cockroach is the closest match we were able to locate on BugGuide, however, the range is listed as:  “Disjuct distribution in North America, occuring in mountainous areas of Oregon and northern California, as well as the Appalachian mountains in the eastern U.S.”  Is your location mountainous, or high altitude?  If our identification is correct, this is not a species of Cockroach that infests homes.  According to BugGuide “This species feeds on rotting logs, and is not a house pest like many other roaches, in fact it might be considered an important recycler of nutrients in decomposing wood.”  Insects are amazingly adept at entering homes through small cracks in the foundation as well as via windows and doors, even if they are not species that find the human comforts to their liking.

I do live at high elevations.  We are located in Fort Collins right next to the mountains.  The roach measured between 50 to 60mm.  Last thing, my wife said it never hissed while she was trying to get it.

Update from Eric Eaton
October 30, 2011
Hi, Daniel:
I agree this is most likely a Madagascar Hissing Cockroach.  The Brown Hooded Roach looks different and does not occur in Colorado.
Eric

Update:  October 31, 2011
If Eric Eaton is correct, the question now becomes how did a Madagascar Hissing Cockroach get under the bed.  Here is what we know:  Boys like bugs.  Madagascar Hissing Cockroaches are available in pet stores and they reproduce well in captivity.  Children play jokes on one another.  We would not discount that either the child living in the home or a visiting friend either intentionally or accidentally released a domesticated Madagascar Hissing Cockroach in the bedroom.

So what are the odds that there are more in my house?  By the way thanks for the help.

We strongly doubt that they are reproducing in your home.

Black and Yellow Bug
Location: Millbrae, CA
August 23, 2011 5:45 pm
Hello,
I found this guy hanging out under the sunny part of my bathroom closet door. It was yesterday, at Millbrae, CA (94030). I can’t figure out what this is. It moved really really super fast like a silver fish does. Its underside was white with a lot of tiny parallel segments. It’s very mysterious, I’ve never seen it before. I thought it was going to move like a lady bug but it did not. It also has long skinny black legs and antenna. What is this? And did he travel here from a flower? Or is from this area? Never seen it in my life.
Thank you! -Crystal

Cockroach

Hi Crystal,
We will identify this Cockroach in the morning.  We really love your photo which would be an excellent image if we ever do another calendar.

PS. I think that two long antennas were actually coming from his butt side.  As you can see, he has a small head and smaller antenna on the other side. When I caught him with my insect looker, he moved forward from the side that is opposite of those 2 really long antennas you see up top.
Crystal

Hi Crystal,
Your Cockroach is
Phyllodromica trivittata, and BugGuide provides some interesting information, beginning with:  “Recently introduced into California, apparently now in Marin, Petaluma and Cotati” and “Reports of high abundance both indoors and outdoors make it likely that reproduction is occurring outdoors with subsequent invasion of nearby structures. As this species adapts to this new environment, studies will need to be conducted to confirm this.”  Here is a final remark regarding its origins:  “Known from dry habitats around the Mediterranean. It has been recorded from Morocco; Algeria; Spain; Italy (Sardinia Island); Italy (Sicily); Libya; and Israel. Given that it has not been recorded as being a pest in buildings in those countries (as far as I’m aware) it is unlikely to invade buildings in the USA. Comment by George Beccaloni (The Natural History Museum, London, UK).”  The head is actually on the side with the long antennae.  The shorter appendages are known as cerci and BugGuide has a nice definition of them.


Thank you for identifying this mysterious creature… but cockroach does make sense, especially its swiftness, its one piece body – which eliminated the cucumber beetle idea, its cerci, and its non-beetle looking underside… it’s a pretty cockroach.  But the idea that it’s a cockroach is kind of creepy, especially because its American cousin is a pest. :)
Thanks again!

Possibly Bed Bugs?
Location: Baltimore City, MD
August 8, 2011 11:44 pm
Dear Bugman,
We found two of these critters alive (on the ceiling) and promptly squashed them. My wife found several dead ones throughout the house (living room, bedroom, kitchen and bathroom). Our floor is carpeted throughout the house except for the kitchen and the bathroom.
I was bitten several days ago but I’m not sure what it was. We believe these are bed bugs. We have also turned our house upside down trying to find their ”home” but we found no clusters of bugs, droppings, or larvae associated with bed bugs. Are they bed bugs and why are we finding most of them dead?
Thanks.

Dear In Fear of Bed Bugs,
The good news is that you do not have Bed Bugs.  The bad news is that you have recently hatched Cockroach Nymphs.

”Mustard” Bug
Location: Manhattan, NY, NY
August 8, 2011 8:17 pm
I bought a pretzel off of a vendor in Manhattan. He put it in a brown paper bag because I was going to take it to go. He didn’t have mustard packets available, but did have a warehouse sized size of yellow mustard on his stand. It’s August and has been consistently humid and a minimum of 85 degrees a day for over a month now. The bottle looked as though it had seen better days, but I figured, once I got upstairs to my office I’d wash my hands after touching it and eat my pretzel. So I proceeded to squeeze some mustard onto the side of the bag and carefully went upstairs, where I tore the bag apart to make a plate and mindlessly ate some pretzel as I worked on my computer. Half way through the pretzel I looked at my mustard and thought, ”what are those green things? Oh no, I hope there’s no dirt in the bag”….ugh! if only it was that good. I moved the ”green things” around and it turns out they were black worms or bugs or larva of some sort. with orange/yellow stripes, legs and antennas! I’m disgusted! I don’t know if it came from the mustard that’s probably been sitting on his cart since the winter, or if they originated from the paper bag and the mustard killed them. Please help me identify these things and let me know that I won’t get a parasite of some sort. I’ve attached pictures.

Dear grossed out,
Your pretzel vendor is serving immature Cockroaches with his pretzels.  We will be tagging your submission as one of the Worst Bug Stories Ever.

Egyptian Desert Roach

Hi MiGo,
This is a female Egyptian Desert Roach,
Polyphaga aegyptiaca.  This is not a species that will infest your home.  You can read all the previous research we did on the Egyptian Desert Roach in this posting from our archives.

Cockroach Eating Cicada

I thought you would enjoy this picture I took one night of a cockroach munching on a cicada while the cicada was molting. Cockroaches are certainly opportunistic.

Wood Cockroach eats molting Cicada

Hi Amelia,
Thank you so much for sending this amazing documentation.  We don’t normally think of Cockroaches as being predators, but this lends credence to the popular concept that they can and will eat most anything.  It appears that the Cockroach might be a Pennsylvania Wood Cockroach based on the markings around the pronotum.  Check BugGuide for a comparison.

Eric Eaton provides and alternate theory
Yep, a male Parcoblatta pennsylvanica.  I’m thinking the cicada is already dead (got stuck while molting) or it is just the exuviae itself.  Roaches are rarely, if ever, predators.
