Insect Order By: cadashia Collins

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


Hymenoptera is the third-largest order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 species are recognized,[1][2] with many more remaining to be described.

Females typically have a special ovipositor for inserting eggs into hosts or otherwise inaccessible places.


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.


Dragonflies and damselflies are predaceous both as immatures and adults. The adults are quick, agile fliers that are generally considered beneficial because they feed on large numbers

Eggs hatch into aquatic immatures (naiads) that feed opportunistically on other forms of aquatic life including mayfly naiads, small crustaceans, annelids, and mollusks.

The compound eyes of some dragonflies may have up to 28,000 facets.


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.


Lepidoptera (butterflies and moths) are holometabolous insects; that is they have four distinct stages in their lives, egg, larva, pupa and adult.

In each stage they look very different, and two of the stages are largely immobile, resting stages

There are around 165,000 species known worldwide, 8,500 in Europe and 2570 in the British Isles, but only 67 of these British species are butterflies; the rest are moths.
