Orthopterida The main defining character of the Orthoptera is the fact that they have the hind legs
adapted for jumping: the femur is broad because it contains muscles for extending the leg
quickly. There are 366 genera and 968 species native to southern Africa.

Acrididae The majority of non-colourful grasshopper
species fall within the family Acrididae. The acridids include the locusts
which are a select group of grasshoppers that are able to pass into a
swarming phase subject to the right environmental conditions. There are 114
genera and 300 species native to southern Africa. |

|
Lathiceridae
Three genera and four species, all endemic to Namibia. |
 |
|
|
|
|
Lentulidae
Endemic to Africa south of the Sahara, mainly southern Africa, where there
are 26 genera and 58 species, most of which are endemic to this subregion. |
 |

|
Lithidiidae
Endemic to southern Africa where there are four genera and
13 species. |

Pamphagidae (toad grasshoppers) Toad grasshoppers occur
in Africa, Europe and Asia. Twenty genera and 69 species native to southern
Africa. They tend to be thick-set, spiny, camouflaged grasshoppers. In many
species the female is wingless. |

This small family consists of four genera, three of which
are endemic to southern Africa (with four species) and one endemic to
Morocco (with one species). |
