insect orders by Ansley Hill

Lepidoptera

Lepidoptera includes moths and butterflies. The name Lepidoptera, derived from the Greek words "lepido" for scale and "ptera" for wings, refers to the flattened hairs (scales) that cover the body and wings of most adults.

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

hemiptera

The hemiptera include, cicadas, aphids, shield bugs, bed bugs, pond skaters, water bugs, cuckoo spit insect and many more.

Have piercing mouthparts, called a rostrum which contains 2 pairs of stylets. The outer 2 pairs (the modified mandibles and maxillae) have serrated edges for piercing, and the labium and labrum form a tube around the stylets for food to pass up and saliva to pass down. The tip pf the rostrum has receptor cells to assess the suitability of the food source.

Odonata

Odonata, dragonflies, damselflies, are also sometimes known as horse stingers, devil's darning needle, which according to superstition will be used to sew up the lips of liars. They are divided into two sub-orders: Zygoptera, the damselflies, and Ansioptera, the true dragonflies.

Large eyes with up to 30,000 ommatidia (facets).

coleoptera

The name coleoptera comes from the Greek words koleos, meaning "sheath" (cover) and pteron, meaning "wing", so "sheathed wing". Beetles have two pairs of wings, the front pair, called "elytra", are hard, thick sheath or shell-like and protect the more normal rear pair of wings which are used for flying.

Around 40% of all known insect species are beetles, this equals about 400,000 species and some estimates suggest there could be as many as 3 - 8 million beetle species on Earth.

orthoptra

Over 19,000 species worldwide, mainly in the tropics, around 1000 in Europe, just 30 in the British Isles, and most of these in the south, 7 in Scotland

Usually 2 pairs of wings in the adult with the front pair tough and leathery and called tegmina.

diptera

True flies have only one pair of membranous wings (a few parasitic species are wingless)

Over 119,000 species have been described world wide, but many more are awaiting description
