Gampsocleis buergeri
A large katydid occurring in both green and brown forms. The male sings with a stridulatory organ on the forewing, and the front legs carry a row of spines longer than the leg is thick. It is strongly omnivorous and will catch and eat other insects.
The katydids called kirigirisu in Japan have, since the 2000s, been treated as two species rather than one. Because the name buergeri is thought to rest on a specimen from Nagasaki, it is applied to the western species, which ranges from the Kinki region to Amami-Oshima. The Japanese Wikipedia gives the western species as 29.0-37.0 mm in males and 30.0-39.5 mm in females, with longer wings and fewer black spots than the eastern species. Both a green and a brown form occur, depending on where the insect grows up. Unlike a grasshopper it is deep-bodied with long legs and antennae, and its hearing organs lie partway along the front legs. The female has a sword-like ovipositor. The first two pairs of legs bear many spines, and the insect is omnivorous enough that it has been recorded preying on a mantis. It is single-brooded, the adults appearing in summer in grassland.

Omnivorous: herbaceous plants and other insects
No published figures for rearing temperature or humidity could be found for this species, so none are given. It lives in sunny grassland from the lowlands to low hills, and since it overwinters as an egg the soil in the container should be kept damp through the winter after laying.
The female lays with the sword-like ovipositor at the tip of her abdomen. The insect is single-brooded and overwinters as an egg, the adults appearing in summer. The eastern and western species occupy different ranges, so do not cross insects from different localities.
It is strongly omnivorous and preys on other insects, so several in one container will eat one another; it has even been recorded taking a mantis. Keep it singly, or at low density with plenty of animal food.
It is single-brooded and lives one year. The adults appear in summer and the eggs carry the population through the winter.
The front legs carry spines longer than the leg is thick and the mandibles are strong, so it may bite if handled bare-handed. A related species occurs in Hokkaido and another in the Okinawa and Miyako islands, so check locality data before housing insects together.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
Japanese Katydid typically reaches Males 29.0-37.0mm, females 30.0-39.5mm (head to wing tip) as an adult. Size may vary depending on care conditions and individual genetics.
Japanese Katydid feeds on: Omnivorous: herbaceous plants and other insects. Aim for a balanced diet with appropriate feeding frequency.
