Blattella germanica
About 12 mm long, this slender cockroach was translucent all over with a broad black band running down the length of the thorax and abdomen on either side. The posterior part of the abdomen tapered to a lance-shape.
Spotted on a wall at a local school. These occur wherever humans are and can't survive without them. The other factor that affects their survival is cold temperature.So,in colder climates they are not able to survive without central heating.
The females have broader abdomens. The "medical and economical significance" in the reference link makes good reading ! Suborder Blattoidea Family: Blattellidae
