Grasshopper (family: Acrididae)
Foaming grasshopper Dictyophorus spumans
(family Pyrgomorphidae). Poisonous!
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
Many people get confused between grasshoppers and locusts usually thinking that a large
grasshopper is a locust. In fact, locusts are limited to a few species of grasshoppers
which go into a swarming phase forming massive swarms that can cause immense destruction
to crops and pastures.
- Suborder: Ensifera (have elongate, bendy, antennae with many segments)
