Grasshoppers, crickets, katydids and locusts all belong to the order Orthoptera which means 'straight wings'. Most are easily recognisable by their hind legs, which are usually enlarged for jumping. They are often easily seen jumping away when disturbed or heard 'singing' at night.
Antennae may be short to very long depending on the species. Grasshoppers have relatively short antennae while crickets and katydids generally have long antennae
Orthopterans develop by incomplete metamorphosis. The majority of orthopterans lay their eggs in the ground or on vegetation
Beetles are a group of insects that form the order Coleoptera, in the superorder Endopterygota
Their front pair of wings is hardened into wing-cases, elytra, distinguishing them from most other insects.
They interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates.
Most hemipterans feed on plants, using their sucking and piercing mouthparts to extract plant sap.
Some species are important agricultural pests, damaging crops by the direct action of sucking sap, but also harming them indirectly by being the vectors of serious viral diseases.
