Smoky Brown Roaches
The smoky brown cockroach is similar to the more common american cockroach but is slightly smaller ranging from 3 - 3.5 cm long. It is a rich mahogany brown color, and the thorax is dark and shiny, which distinguishes it from the lighter thorax of the american cockroach. Female smoky brown cockroaches are slightly larger than males.
The smoky brown likes warm, humid conditions, and as such, it is found over most of Honshu, Kyushu, and Okinawa, as well as in the southern United States. It tends to base itself in warm spots outdoors, and from there it invades buildings and houses. This roach needs access to liquid water every 2-3 days because it loses moisture through it's outer layer of skin. In Japan, this means that the smoky brown is not as common in houses as other types of cockroach because many houses have air conditioning, which keeps humidity levels down.
