    Brown-Hooded Cockroach - (Cryptocercus punctulatus)

    The woods of the Appalachian mountains and the Pacific Northwest are the home of the Brown-Hooded Cockroach, unlike its cousins which prefer the dwellings of humans.

    Staff Writer (6/2/2017): Not all cockroaches desire to live among humans. The Brown-Hooded Cockroach is a woodland cockroach that prefers the great outdoors to kitchen cabinetry.

    This small, social insect lives in large congregations inside and around decaying tree trucks, stumps and limbs. Keeping the generations together is the only way of keeping the population alive. Nymphs of the Brown-Hooded Cockroach are hatched without the ability to digest cellulose, the chief component of plant cells. Their diet is decaying wood, so nymphs need a way to break down wood. Adults rely on cellulose-destroying protozoans in their digestive organs in order to glean nutrition from the wood. In order to ingest the same necessary protozoans, the nymphs must feed on the fecal matter of adults. Without the feces, which harbors the living protozoans, the nymphs would essentially starve to death.

    The Brown-Hooded Cockroach does not enter buildings with the intention of living there like other nuisance cockroaches. It is not considered a pest. The outdoors is their preferred domain. As rotting wood is both their habitat and food, it is likely to be found in woodlands and forests with fallen trees and broken branches that likely hold many others of its kind.

    BUGFINDER: What Kind of Bug is This...
    BUGFINDER allows for a quick search of the Insect Identification database by selecting primary color, secondary color, number of legs and the territory / state in question. If only one color is present on your insect, select it again as its SECONDARY color. Remember that the more details you can offer, the better your chances of finding a match. As a rule of thumb, six legs are typical for most insects whereas spiders generally have eight legs.
