Locusta migratoria
A large 35-65mm grasshopper in green or brown forms, with mottled brown-and-white forewings and plain hindwings. At high density it turns gregarious and swarms. It is kept and bred both as live food and for observation.
Locusta migratoria (Linnaeus, 1758) is the only species in its genus and the most widespread locust, occurring across Africa, Europe, Asia, Australia and New Zealand; in Japan it is found nationwide. It is 35-65mm long, females being larger, with mottled brown-and-white forewings. It comes in green and brown forms, and develops a solitary phase at low density and a gregarious phase at high density; gregarious swarms can strip crops, and outbreaks have occurred in Japan, for example in Okinawa. It lives in sunny, grass-rich grassland from plains to low hills, mostly on riverbanks in Japan. It eats grass leaves but also dead insects, and often attacks members of its own species that are stuck mid-moult. Females push the abdomen into soil to lay a spongy egg pod. There are two generations a year: summer eggs hatch in about a month, while autumn eggs overwinter and hatch the next spring. The Tsushima population is on Nagasaki Prefecture's Red List. In Japan wild-caught insects are kept, and captive-bred locusts are sold as live food for reptiles and other pets.

Not covered by CITES or the Invasive Alien Species Act. In its gregarious phase it damages crops, so keep feeder colonies escape-proof and never release them. Bringing live foreign stock into Japan requires checking with the Plant Protection Station first whether it counts as a pest.

Herbivorous (mainly grass leaves)
Keep at 25-35C by day, letting it fall to about 15C at night. It needs warm, dry conditions; damp enclosures lead to disease and death. Use dry sand or coconut fibre and do not mist.
It chews through fabric and netting, so use a sturdy enclosure with metal mesh ventilation. Allow at least about 50x50x30cm for twelve adults, add dry twigs as perches and let light in.
Feed mainly fresh grasses; it takes its water from food, so at most lightly mist the grass before feeding. Grass treated with insecticide is deadly. Tama Zoo feeds maize leaves and sorghum.
Females push the abdomen into soil to lay egg pods, so provide a container of soil or sand. Eggs hatch in two to three weeks, nymphs reach adulthood in about four weeks and start breeding about two weeks later; cold slows everything. Moulting individuals are often eaten, so avoid overcrowding.
Adults die of age about five months after the final moult. In the wild there are two generations a year, with autumn eggs overwintering to hatch in spring.
In its gregarious phase it can erupt and damage crops, so keep feeder colonies escape-proof and never release them. The Tsushima population is on Nagasaki's Red List. Importing live foreign stock needs prior clearance from the Plant Protection Station.
