Physical characteristics: Adults measure 0.35 to 0.5 inches (8.9 to 12.7 millimeters) in length. Males have toothed jaws and reddish brown bodies, while the females are chocolate brown.

Geographic range: This species is native to north central India but is now widespread throughout the tropical regions of the world, as well as parts of the southern United States and Southeast Asia.

Habitat: This species is commonly found on trunks of rainforest trees, as well as on royal palms in gardens and parks.

Diet: They eat lichens (LIE-kuhns) or mosses and algae (AL-jee), tiny plantlike organisms, growing on the bark of tree trunks.

Behavior and reproduction: This species lives in colonies made up primarily of mothers and their offspring. The females guard the eggs. Gallery surfaces are almost completely camouflaged with webspinner waste or finely chewed pieces of wood and bark. Winged males are commonly attracted to lights.
