The Question Mark Cockroach (Therea olegrandjeani) is an insect.
The Question Mark Cockroach is black with white markings that look like question marks. Its flattened oval-shaped body has three sections: a head with mouth parts and antennae; a pronotum (a plate-like shield); and an abdomen. Its six legs have spikey hairs on them.
It measures 2-3 centimetres (1 inch) long.
The Question Mark Cockroach is native to India. It prefers moist, warm, dark areas, such as leaf litter, tree bark, and scrub forests.
It is omnivorous, eating fruit, dead animals, and vegetables. It is also a detritivore, eating kitchen waste.
The Question Mark Cockroach begins its life as an egg, then a nymph, and then an adult cockroach. Females lay about 10 eggs at a time in a case called a ootheca, which hatch after 6-8 weeks into nymphs. The nymphs eat and moult as they grow into adults.
