How to Identify Brown-Banded Cockroaches
The brown-banded cockroach (Supella longipalpa) is small and light brown in coloration with a length of about half an inch - 13 to 15mm in length. It has two broad white stripes on both wings and abdominal segments, making it a special characteristic of this insect.
These bands are more defined in nymphs and females and hence should be used as the defining criteria.
Males vs. Females
They are sexually dimorphic with male insects being thin with broad wings that conceal the abdomen, which they can use for short hovering flights in case of any disturbances. Males are smaller and possess wings that do not span until the abdomen’s region, while females are broader and do not fly.
Nymphs
Frogs are larger, less developed in the limbs, have no wings, and are generally darker in color compared to nymphs, which have more contrasting banding. Adults are a drab greyish color, while one of the defining characteristics of the species remains the presence of black bands on their legs.
Behavior
Contrary to other cockroach species that are known to thrive in dark and damp conditions, brown-banded cockroaches are known to be attracted to warm and dry conditions. Rodents are often located in the upper sections of a dwelling, on walls, ceilings, or within electrical appliances.
It may also involve infesting furniture, picture frames, and behind wallpapers. This behavior of roaches residing in high-up places makes them easily recognizable from others such as the German cockroach which requires humid areas to live in.
Habitat
Brown-banded cockroaches are usually found in warmer environments with temperatures of about 80°F (27°C) and unlike other cockroaches, they are capable of surviving in environments that may be devoid of water.
It is common to find them in places like bedrooms, living rooms, and office spaces which can help you identify if they are around.
