Domino Roach (Therea petiveriana)

Therea petiveriana

The Therea petiveriana (Domino Roach or Domino Cockroach). It is a true masterpiece of nature: a small Asian roach (about 1 inch) that does not look at all like a cockroach, but perfectly imitates the color pattern and gait of a poisonous beetle (Anthia or Sand Carabid). It is round, stubby, with velvety black wings studded with showy and perfect round spots of a Pure White (hence the name 'Domino'). Beautiful as adults, the nymphs are dusty-gray and live strictly buried underground. Breeding is very easy but requires a lot of patience: the substrate must be partially sandy/arid on the surface and the nymphs take up to a year and a half to perform the last molt that gives them the magical domino colors. They are diurnal, love to run around on dry corks in search of pollen, sugary fruit and dead leaves.
