Chewing lice live among the hairs or feathers of their host and feed on skin and debris, while sucking lice pierce the host’s skin and feed on blood and other secretions. They usually spend their whole life on a single host, cementing their eggs, which are known as nits, to hairs or feathers. The eggs hatch into nymphs, which moult three times before becoming fully grown, a process that takes about four weeks.
Humans host three species of louse, the head louse, the body louse and the pubic louse. The body louse has the smallest genome of any known insect; it has been used as a model organism and has been the subject of much research.

Grasshoppers are insects of the suborderCaelifera within the order Orthoptera, which includes crickets and their allies in the other suborder Ensifera. They are likely the oldest living group of chewing herbivorous insects, dating back to the early Triassicaround 250 million years ago. Grasshoppers are typically ground-dwelling insects with powerful hind legs which enable them to escape from threats by leaping vigorously. They are hemimetabolous insects (they do not undergo complete metamorphosis) which hatch from an egg into a nymph or “hopper” which undergoes five moults, becoming more similar to the adult insect at each developmental stage. At high population densities and under certain environmental conditions, some grasshopper species can change colour and behaviour and form swarms. Under these circumstances they are known as locusts.

Insects in the familyTettigoniidae are commonly called bush crickets[2] (in the UK), katydids (in the USA), or long-horned grasshoppers (mostly obsolete). More than 6,400 species are known. Part of the suborder Ensifera, Tettigoniidae is the only family in the superfamily Tettigonioidea.
Primarily nocturnal in habit, with strident mating calls, many katydids exhibit mimicryand camouflage, commonly with shapes and colors similar to leaves.[3]

The ant-loving crickets are rarely encountered relatives of crickets, and are obligate inquilines within ant nests. They are very small, wingless, and flattened, therefore resembling small cockroachnymphs. There are a few genera, containing fewer than 100 species. Ant Crickets are yellow, brown, or nearly black in color. They do not produce sound, and lack both wings and tympanal organs (“ears”) on the front tibia.
