 Gordon's Orthoptera Page
The Orthoptera are a group of large and easily recognised insects which includes the Grasshoppers, Locusts, Groundhoppers, Crickets, Bush-crickets (called Katydids in America), Mole-crickets and Camel-crickets as well as some lesser groups.
Though most of the Orthoptera will eat vegetable matter of some sort only Grasshoppers, Groundhoppers and a few rare Bush-crickets are are predominantly herbivorous (eat only plant material) most of the rest are omnivorous (eating both plants and animals) eating whatever comes there way.
The Orthoptera are renowned for the songs and in some Eastern countries males (females generally do not sing)are kept in small cages specifically so that the keepers can enjoy their song.

 Singing Orthoptera in Japanese Culture, Cultural Entomology Digest 3
The Japanese have a long tradition of enjoying the calls of various Orthoptera, both in the wild and as caged pets (Lafcadio Hern, 1905, Exotics and Retrospectives, Little, Brown and Co., Boston).
These terrariums are sold to keep and rear a few species of singing Orthoptera (mainly the bell insect, Homoeogryllus japonicus de Haan), which are also sold along with specially packaged bell insect food and soil in pet shops.
Recordings of singing Orthoptera are sold in record stores, and can be heard in subway stations and other public places.
