I encounterd this insect in a public bathroom. I suspect it might be a cockroach but I have never seen anything like this. I do not know if the brown shell is another insect or an egg. I am very eager to know what insect this is.

Metamorphosis of a Cockroach

Metamorphosis of a Cockroach

Dear Zayd,
You witnessed the metamorphosis of a Cockroach.  Unlike the literary Franz Kafka version where a man is transformed into a Cockroach, the metamorphosis process is a natural means for insects and other creatures to grow and mature.  Insects and other Arthropods have hard exoskeletons that do not grow.  When the insect outgrows its exoskeleton, it molts, shedding the old skin, and then the insect expands in size.  In your image, the old exoskeleton is dark and the new exoskeleton is white and soft.  It will soon darken and harden and the Cockroach will be larger than before the metamorphosis.

Australian Cockroach

Australian Cockroach

Dear Grant,
At first we were going to send a brief response that this is a Cockroach, but we decided the thoracic markings are so striking that we would attempt to identify the species of Cockroach you encountered.  After finding several similar looking images that only identified it as a Cockroach, we found the Suffolk Pest Control Company that identified it as an Australian Cockroach,
Periplaneta australasia., and that provided this information:  “Inspite of their exotic origins Australian cockroaches are making a home for themselves in the UK, where they can found in most major cities.”  Not confident that the Australian Cockroach is actually native to Australia, we found this information on BugGuide:  “Adult has thorax outlined in yellow with black/brown center marking somewhat like a sideways number eight. Differentiating Australian cockroaches from other species of Periplaneta requires identification of the narrow yellow mark along front outside edge of wings”, but nothing was written about the country of origin.  The garden is calling us from additional research at this time.

Hi Daniel
Thanks for your help. Am guessing we need to contact some form of pest control company as they seem quite dangerous.
Because we d found one , I suppose there are more so will get onto it straight away.
Thanks again
Grant

Hi Bugman,
My wife found these bugs under our couch cushion and on the wall in our new apartment in Dongguan, Guangdong, China. This located in southern china and it’s January.
I can’t seem to find any pictures or information on what these could be from my research online — can you help identify these? Should she be worried?

Immature Cockroach

Immature Smokey Brown Cockroach

Dear Ryan,
This is an immature Smokey Brown Cockroach, a species that according to the Orkin site:  “They prefer nondwelling areas such as greenhouses, nurseries and gardens but can be an indoor pest. They can be found throughout the southern United States and are most common from Texas to Florida. They have also been found in Southern California. They are major pests in cities such as Houston and New Orleans.”  Many species of Cockroaches that have adapted to living with or near humans now have cosmopolitan distributions, and it can be difficult to trace their place of origin.  We are having a difficult time tracking down information on the distribution of the Smokey Brown Cockroach, and though we don’t normally cite Wikipedia, that universal source of information states:  “The smokybrown cockroach is very common in Japan, as well as the southern United States and tropical climates; notably, it can be found in Florida, Louisiana, Mississippi, Texas, and other moist Gulf coastal states, and along the southern Mississippi River.”
  The Biodiversity Heritage Library published an article entitled “The pest status of Periplaneta fuliginosa (Serville) (Dictyoptera: Blattidae) in China”.

Hi Daniel,
Thanks for the reply and ID. Apologies for the late response and thank
you…hard to access gmail in China.
Great to know that these were in fact cockroaches — never experienced
them in the US. When some of my Chinese friends said they were
cockroaches, I didn’t know if they were or not because I’ve only seen
pictures of mature ones.
Got an exterminator and cleaned up the hidden areas, so my wife isn’t
quite as angry anymore. I’m sure summer will bring more surprises.
Thanks again!
Ryan

Hi! This is a follow-up submission with another couple of photos. The roach is not B.dubia. It doesn’t have the same markings, shape of pronotum is different, and it climbs glass. So WHAT is it? It is from Central America. Not an indoor pest. Very uncommon.

Brownbanded Cockroach

Brownbanded Cockroach

Dear Jon,
We believe we have correctly identified your Cockroach as a Brownbanded Cockroach,
Supella longipalpa, based on this image posted to BugGuide.  According to the Penn State Entomology site:  “Brownbanded cockroaches prefer warm and dry locations, such as near refrigerator motor housings, on the upper walls of cabinets, and inside pantries, closets, dressers, and furniture in general. They can also be found behind picture frames and beneath tables and chairs, and inside clocks, radios, light switch plates, doorframes, and dressers. It is common to find them hiding nearer the ceiling than the floor and away from water sources. Accurate identification is paramount to controlling brownbanded cockroaches. Control strategies for other cockroaches will not be efficacious for brownbanded cockroaches.”

Thanks Daniel, that looks so right.
I’ve contacted the apartment manager to send in an exterminator and have a look at it,
Happy holidays!
Jon

Dear TVenters,
This is an immature Cockroach, and if they have just begun appearing in your home, we would speculate they were recently introduced with groceries, laundry or some other load that you returned home transporting.
