Crickets and Katydids

Order Orthoptera, Suborder Ensifera

This page contains pictures and information about Crickets and Katydids that we found in the Brisbane area, Queensland, Australia.
Crickets and katydids are in insect Order Orthoptera, Suborder Ensifera. They are among the most commonly seen insects. Their size ranges from 5mm to 100mm. They usually have very long hair-like antenna, usually longer than their body length. Most of them have the hind legs highly developed, much stronger and larger than the front two pairs of legs. They are good in jumping.

Classification :

In the Orthoptera Order, the are two suborder: the Suborder Ensifera (Crickets and Katydids) and Suborder Caelifera (Grasshoppers), each of which contains a numbers of families. Followings are the list of Ensifera families that we found up to this moment. 
Suborder Ensifera
Members in this Suborder have very long antennae, some may be several times of their body length. The auditory organs located on the fore legs. Their stridulation are produced by the mechanisms on the base of their forewings. The females usually have long ovipositors extended from the end of their abdomen.
Family GRYLLACRIDIDAE - Raspy Crickets
Members in this family, including nymphs and females, will produce a raspy sound when disturbed. They are active at night. They usually spend the daytime in burrows or in leaves shelters.
Family TETTIGONIIDAE - Katydids
In this family, nymphs are usually resemble ants or bugs. Females have sword-like ovipositor and lay eggs by inserted them into leaf. Males produce love songs by file on the left wing and scraper on the right. Most of them are tree foliage feeders. A few of them are predaceous species.
Family GRYLLIDAE - True Crickets 
The True Crickets can be distinguished from others by presence of long ovipositor and long cerci in females. They are nocturnally active. They live on the ground, can be found in burrows, crack in soil or amongst leaf litter. Males produce complex love songs by rubbing wings together.
Family GRYLLOTALPIDAE - Mole Crickets 
Mole Crickets have characteristic digging forelegs. Males produce songs and build burrows to amplify their love song. When dug up, they do not leap away like other burrow-inhabiting insects but dig their way back underground with powerful strokes of the forelegs. The dirt is simply forced aside. Their antennae are relatively short.
