Ensifera is a suborder of insects that includes the various types of crickets and their allies including: true crickets, camel crickets, bush crickets or katydids, grigs, weta and Cooloola monsters. This and the suborder Caelifera (grasshoppers and their allies) make up the order Orthoptera. Ensifera is believed to be a more ancient group than Caelifera, with its origins in the Carboniferous period,[2] the split having occurred at the end of the Permian period.[3] Unlike the Caelifera, the Ensifera contain numerous members that are partially carnivorous, feeding on other insects, as well as plants.
Ensifer is Latin for "sword bearer", and refers to the typically elongated and blade-like ovipositor of the females.[4]
Characteristics
Characteristics shared by the two orthopteran suborders, Caelifera and Ensifera, are the mouthparts adapted for biting and chewing, the modified prothorax, the hind legs modified for jumping, the wing shape and venation, and the sound-producing stridulatory organs.[2]
Ensiferans are distinguished from Caeliferans by their elongated, threadlike antennae, which are often longer than the length of their bodies and have over 30 segments (except in the subterranean Cooloolidae family). For this reason, they are sometimes referred to as "long-horned orthopterans". In the families in which the males sing, the fore wings have modifications that include toothed veins and scrapers for making the noise, and the surrounding membranous areas amplify the sound. In these groups, the sound-detecting tympanal organs are located on the tibiae of the front legs.[5] The tarsi have three segments and the ovipositor is blade-like or needle-like. The male attaches the spermatophore externally to the female's gonopore. The spermatophore is often surrounded by a proteinaceous spermatophylax, the function of which is to provide a nutritional nuptial gift to the female.[5][6]

Phylogeny
The phylogenetic relationships of the Ensifera, summarized by Darryl Gwynne in 1995 from his own work and that of earlier authors,[lower-alpha 1] are shown in the following cladogram, with the Orthoptera divided into two main groups, Ensifera and Caelifera (grasshoppers). Fossil Ensifera are found from the late Carboniferous period onwards.[5][10]
The oldest known fossil in the Archaeorthoptera, the crown group of the Orthoptera, and also the oldest member of the Pterygota (winged insects), is from the Namurian (324 mya) Lower Carboniferous beds in the Upper Silesian Basin of the Czech Republic.[11]
