We live in Tulsa, OK and today I found this small bug. His body was perhaps 1/4” long. And no, we do not have a live Xmas tree.
Thanks for your help identifying this visitor!

Cockroach Nymph

Dear Trixie in Tulsa,
We hate to be the bearer of bad news, but you have an immature Cockroach.  Since it is not mature, you do not have to worry about it reproducing, however, it may have siblings or parents also living in your home.  It appears from your second photo that the Cockroach is contemplating a dash into the kitchen where there is food stored, no doubt.

We have been fighting the cockroaches for months thanks to some trashy neighbors, but this one looks different than the others.  Also, we haven’t seen any roaches for several weeks so we were sort of hoping we were finished with them!

Metamorphosis of a Cockroach

Dear english,
We wish your photo had more detail.  We believe you have photographed the metamorphosis of a Naiad, the aquatic nymph of a flying insect with incomplete metamorphosis.  Some insects that have larvae known as Naiads include Dragonflies, Damselflies, Mayflies, and Stoneflies.  There is something that does not seem quite right about any of those possibilities.  The head of this insect looks almost like that of a Grasshopper, but the hind legs are not long enough for a Grasshopper.  It it turns out that this is the metamorphosis of some land insect like a Cricket, then this would be a documentation of the Metamorphosis of a Nymph, which is a term with a larger umbrella.  All Naiads are nymphs, but not all nymphs are Naiads.  This Tree Cricket Information page with photos and videos is pretty awesome.

Update: 
We just received a comment that believes this may be a Cockroach Metamorphosis.  That is a very good possibility.  The morphology looks correct.

Never seen this one before. Looks like a roach from the underside, but it’s topside is like a giant flat doodle bug with fewer segments. It has a reddish ”tail”, maybe a female. It’s not ver clear from the photo. Burrowed in the grass/ground to hide.

Boll’s Sandroach

Dear K Bernsen,
While you are correct that this Boll’s Sandroach is a Cockroach, it is not a species that infests homes.  This is a wingless female Boll’s Sandroach, 
Arenivaga bolliana, or another member of the genus.   Males, which are capable of flying, are frequently attracted to lights.  According to BugGuide:  “The downy females have no wings and burrow in the dust under houses and in natural rock shelters where they feed on packrat droppings.”  We believe the reddish “tail” is an ootheca or egg case.  The female will carry it about until she finds a suitable place to deposit it.

Hi,
This summer I have had somewhat of an infestation of these bugs outside my house. If I set a box outside on the ground, they would infest the box. Have not seen many recently, but keep seeing them occasionally skittering across my second floor kitchen on the counter. Now I need to find out what they are, what they eat and why they are coming indoors. This is one I whacked on my counter. Fortunately, I did not totally smash it. Thank you in advance for your help.

Dear Daniel,
Thank you so very much for your prompt response. I think that your website is fantastic. That is why I had to send you a pic for ID. It was taking me way to long. I was only on the 24th page of beetles after two hours of looking. Due to my seriously inquisitive ADD nature, I just had to keep stopping and reading about every interesting pic. At the rate I was going, I was never going to ID this critter…….lol.  I now have your site bookmarked for further pleasure reading. Great work you have done!
Now that I have identified it further as the Phyllodromica trivittata (courtsy of your website), I do not think I need to take any further eradication action at this time. From all I have read so far, they do not seem to really be a household pest. sightings in the house have been sporadic. If that changes in the future though, I will go after them. I will see how it goes next summer.  I hope you have a great day!
Sincerely,
Karen

Hi Karen,
Thanks for the followup.  Your letter was one of our attempts to respond to as many requests as possible, hence the short ID.  We are happy you learned the identity of your immature Cockroach on our site and that you have decided not to take any eradication measures, but we are most happy to hear that you have found our archives interesting.  Your response really made our morning and we sifted through the trash to fine your original request so that we could make a posting.  Here is what BugGuide states about this species:  “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.”
  BugGuide continues with:  “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).”  As a note, we always tend to worry about introduced species that thrive in a new environment as they can displace native species and reduce species diversity once they become established.

Daniel,
Here is a good link to send out for this bug to people in California. Some great pics. Invasive species are a good argument against global commerce.

i found it!
on  your site…looks like a cave cockroach.
it was very pretty.

Cockroach

Dear curious,
This is indeed a Cockroach, but it is not a Cave Cockroach.  We may be wrong, but it looks more to us like an American Cockroach.  According to BugGuide:  ” They are significant pests throughout the world. They are not native to the Americas at all. They come from tropical Africa. They were probably transported to the Americas on slave ships.”

Hi Mr. Marlos,
I’m an entomologist living in the San Francisco Bay Area and I just wanted to drop you a line to let you know that I have found Phyllodromica trivittata in Vallejo in Solano County and that it probably came in on wood a friend brought me from Walnut Creek in Contra Costa County. It appears our friend is spreading quite quickly.

Introduced Cockroach

Hi Greg,
Thanks for informing us about the range expansion of this introduced species of Cockroach.  According to BugGuide, it is already reported from California and Nevada.
