Apterygota are a subclass of small, agile insects, distinguished from other insects by their lack of wings in the present and in their evolutionary history. They include Thysanura (silverfish and firebrats). Some species lacking wings are members of insect orders that generally do have wings. Some do not grow wings at all, having "lost" the ...
Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies (which constitute the other odonatan suborder, Epiprocta) but are usually smaller and have slimmer bodies. Most species fold the wings along the body when at rest, unlike dragonflies which hold the wings flat and away from the body.
Tick questing heights tend to be correlated with the size of the desired host; nymphs and small species tend to quest close to the ground, where they may encounter small mammalian or bird hosts; adults climb higher into the vegetation, where larger hosts may be encountered. Some species are hunters and lurk near places where hosts may rest.
Louse (pl.: lice) is the common name for any member of the clade Phthiraptera, which contains nearly 5,000 species of wingless parasitic insects. Phthiraptera has variously been recognized as an order, infraorder, or a parvorder, as a result of developments in phylogenetic research. [1][2][3] Lice are obligate parasites, living externally on ...
Woodlouse. Woodlice are terrestrial isopods in the suborder Oniscidea. Their name is derived from being often found in old wood, [2] and from louse, a parasitic insect, [3] although woodlice are neither parasitic nor insects. Woodlice evolved from marine isopods which are presumed to have colonised land in the Carboniferous, though the oldest ...
Psocodea contains around 11,000 species, divided among four suborders and more than 70 families. [1][2][8] They range in size from 1–10 millimetres (0.04–0.4 in) in length. The species known as booklice received their common name because they are commonly found amongst old books —they feed upon the paste used in binding.
Bookworm is a general name for any insect that is said to bore through books. [1][2] The damage to books that is commonly attributed to "bookworms" is often caused by the larvae of various types of insects, including beetles, moths, and cockroaches, which may bore or chew through books seeking food. The damage is not caused by any species of worm.
A cluster of females. Cochineal insects are soft-bodied, flat, oval-shaped scale insects. The females, wingless and about 5 mm (0.20 in) long, cluster on cactus pads. They penetrate the cactus with their beak-like mouthparts and feed on its juices, remaining immobile unless alarmed.
