The bands may be partly obscured by the wings. The male has wings that cover the abdomen, while the female has wings that do not cover the abdomen completely. The male appears more slender than the female, the female appears wider.
The brown-banded cockroach has a fairly wide distribution, being found in the northeastern, southern, and midwest regions of the United States quite commonly. They are one of the most recent alien cockroaches to form breeding colonies in Britain and Ireland. They need less moisture than the German cockroach so they tend to be more broadly distributed in the home, such as in living rooms and bedrooms. They can often be found in homes and apartments, but are less common in restaurants. They tend not to be found in the daytime, since they avoid light.
In an experiment by Tsai and Chi they found that populations of brown... Wikipedia →

Rare
Under 5% of wildlife watchers report a Brown-Banded Cockroach sighting in Singapore on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 589th most-seen of the 1045 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Brown-Banded Cockroach in Singapore on a given day, so our monthly data shows no clear season.
30th of 34
Of the 34 cities where we can rate Brown-Banded Cockroach sightings, Singapore ranks 30th at under 5%. The best odds are in São Luís (Brazil, about 30%), Vasai-Virar (India, about 30%) and Phnom Penh (Cambodia, about 20%).
GBIF citizen-science records
It is estimated from how often the Brown-Banded Cockroach is recorded against all the insects logged in Singapore (18 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
