Colossopus grandidieri

Colossopus grandidieri is a nocturnal bush cricket endemic to southwestern Madagascar. C. grandidieri appears to be omnivorous and is the only member of its genus that has been bred successfully in captivity, with a diet including leaves, fruit, living and dead insects, and processed food including dog food and fish flakes.

Description
The pale brown, cigar-shaped eggs are deposited singly in soil, measuring only 6 mm when laid and swelling in size as they develop over three months to a year. Females lay 150 to 200 eggs in a lifetime. Adult females and males have similar coloration, except that the labrum ("upper lip") is orange-red in females and yellow-orange in males. When confronted, adults rear up on their hind legs, spread their forelegs, and open their mandibles in a defensive posture. Adult males make a shrill noise when in this position, and adult females do not make a sound. If the disturbing organism approaches, C. grandidieri attempts to grab it with the forelegs and bite it with the jaws.
