Psocoptera (/ s oʊ ˈ k ɒ p t ər ə /) are a paraphyletic group of insects that are commonly known as booklice, barklice or barkflies. [1] The name Psocoptera has been replaced with Psocodea in recent literature, with the inclusion of the former order Phthiraptera into Psocodea (as part of the suborder Troctomorpha ).

The order Psocoptera (also known as Corrodentia) contains the booklice and barklice. These insects are often regarded as the most primitive hemipteroids alive today because their mouthparts show the least modification from the primitive mandibulate condition.

Although they are called lice, the Psocoptera are free-living insects, not parasites. The scientific name comes from the Greek psocus (to grind) and pteron (wing) and refers to the psocopteran jaws, which are shaped to grind food, rather like a pestle and mortar.

Dec 12, 2024 · Psocoptera, Copeognatha, Corrodentia, Mallophaga, Anoplura Note: Information on this page does not fully reflect the incorporation of the parasitic lice , formerly often treated in separate orders, Mallophaga (chewing lice) and Anoplura (sucking lice).

The Psocoptera are tiny insects with chewing mouthparts that have either four wings or none. Why the name 'chewing wing' was assigned is unknown and is one of the few names that do not add usefulness to the taxonomy of insects. Psocopteran metamorphosis is gradual.

The Psocoptera are tiny insects that have either four wings, two wings or none at all. They have chewing mouthparts and a gradual metamorphosis, the life stages being the egg, nymph, and adult. Most species occur outdoors on plants, or under bark, stones or dead leaves.

Psocoptera are tiny insects that have either four wings or none at all. Wings are held tent-like over the back of the body. They generally have long antennae and soft bodies.

Psocoptera are an order of winged insects that are commonly known as booklice, barklice or barkflies. They first appeared in the Permian period, 295–248 million years ago. They are often regarded as the most primitive of the hemipterans. Their name originates from the Greek word psokos meaning gnawed or rubbed and ptera meaning wings. There ...

The insects of the order Psocoptera (=Copeognatha, Corrodentia) are commonly called psocids, although outdoor species living on tree trunks and branches have been called bark-lice, whereas indoor species, sometimes found in old books, have been called book-lice.

Psocoptera: booklice. Characteristics Psocids or booklice as they are commonly known are small usually dull coloured insects with a body length of 1-10 millimetres. All psocids possess silk glands and in some species large webs are formed in which the community lives.

Apr 12, 2020 · The Psocoptera are a group of small, soft, stout bodied insects which include Book Lice Liposcelis sp. which feed on the paste and bindings of old books, as well as on the fungi which invades the pages. They will also feed on museum specimens if given the chance.

of the order Psocoptera, which contains about 3,200 species worldwide. About 30 species from the booklice family, Liposcelidae, occur in North America. Booklice are flat, pale, yellowish or grayish-white, soft-bodied, and 1-4 mm long (Fig. 1). The head and abdomen are large relative to the thorax. They have

Psocoptera are an order of insects that are commonly known as booklice, barklice or barkflies. They first appeared in the Permian period, 295–248 million years ago. They are often regarded as the most primitive of the hemipteroids.

Jan 1, 2009 · Psocoptera (Corrodentia, Copeognatha) constitutes an order of neopterous, exopterygote insects commonly called psocids, barklice, or booklice. Their closest relatives are the Phthiraptera or true lice. Psocids are small and soft-bodied and therefore have received little attention from collectors.

The Pscocoptera have long been regarded as phylogenetically close to the Phthiraptera, but recent research has suggested that the Phthiraptera may even be a subgroup of the Psocoptera, within the wider group of Psocodea.

Fast facts about Psocoptera (book lice, bark lice, dust lice) Minute (less than 6mm) though a few are as large as 10mm, soft-bodied, winged and wingless. Forewings longer than hind wings, and usually extend to completely cover the abdomen

Mar 15, 2019 · Psocoptera, commonly known as “barklice” or “booklice”, have about 10 000 described species from all over the world. Although the Psocoptera are called “lice”, they are not parasites, instead they are free living insects.

Psocoptera are an order of winged insects that are commonly known as booklice, barklice or barkflies. They first appeared in the Permian period, 295–248 million years ago. They are often regarded as the most primitive of the hemipterans .

Classification note: The barklice, booklice and barkflies were once described in their own order, called Psocoptera, but have now been combined with the former orders Mallophaga and Anoplura, and all now fall within the newly named order Psocodea.
