Tettigonia orientalis
A green katydid about 45-55mm from head to wingtip with a brown stripe along the back. Built for life in trees, it becomes more carnivorous as it grows and will pounce on insects its own size.
Tettigonia orientalis Uvarov, 1924 is a katydid (Tettigoniidae) found almost throughout Japan except Okinawa and the Nansei Islands. It measures about 45-55mm from head to wingtip. It is normally green, rarely all dark brown, with a brown stripe running along the back from crown to wingtips. It resembles Gampsocleis but has a smaller body excluding wings and shorter hind legs, a compact build suited to life in trees, while its jaws and leg spines are longer and more specialised for predation. The female's ovipositor is long and straight. It lives mainly in trees and is common wherever vegetation is thick. Young nymphs eat pollen and petals on flowers, but become more carnivorous with each moult, and near the final instar the mandibles take up almost half the face. It sings a 'shiririri' at night and a 'gii' by day. Eggs hatch around April and nymphs mature in about two months. Adults usually live about two months, but captives may survive past the new year. The classification of subspecies and local forms such as the montane yama-yabukiri is unsettled. In Japan singing-insect specialists sell adults and nymphs in season.

Omnivorous, increasingly carnivorous with age (insects, leaves, fruit, pollen)
It lives mainly in trees, so provide branches and foliage and a tall container. It avoids permanently muddy and very dry places, so avoid both stuffiness and excessive dryness.
It eats almost anything, from insects and other small animals to leaves, fruit and buds. Young nymphs eat pollen and petals and become more carnivorous as they grow, so add live prey. Avoid salty food and one-sided diets.
Females and late nymphs are especially voracious and may pounce on and eat animals as large as themselves or larger, so keep them singly.
Females come down to the ground and lay eggs one at a time in soil with the ovipositor. Some eggs overwinter twice before hatching. Eggs hatch around April, and nymphs usually moult six times.
Nymphs take about two months, maturing in the Kanto region around mid rainy season. Males take about ten days after the final moult to start singing properly. Adults usually live about two months, but captives may survive past the new year.
It is often confused with Gampsocleis and Hexacentrus, but the brown dorsal stripe and the similar wing shape in both sexes set it apart. As a native species, never release captives away from where they came from.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The average lifespan of Japanese bush cricket is Adults usually about 2 months (captives may live past the new year). With proper care and nutrition, they can live a long and healthy life.
Japanese bush cricket typically reaches About 45-55mm from head to wingtip as an adult. Size may vary depending on care conditions and individual genetics.
Japanese bush cricket feeds on: Omnivorous, increasingly carnivorous with age (insects, leaves, fruit, pollen). Aim for a balanced diet with appropriate feeding frequency.
