The caddisflies (order Trichoptera) are a group of insects with aquatic larvae and terrestrial adults. There are approximately 14,500 described species, most of which can be divided into the suborders Integripalpia and Annulipalpia on the basis of the adult mouthparts.

Caddisfly, (order Trichoptera), any of a group of mothlike insects that are attracted to lights at night and live near lakes or rivers. Because fish feed on the immature, aquatic stages and trout take flying adults, caddisflies are often used as models for the artificial flies used in fishing.

The order Trichoptera (caddisflies) is another likely descendant of the Mecopteran lineage. Adults are mostly nocturnal, weak-flying insects that are often attracted to lights. During the day, they hide in cool, moist environments such as the vegetation along river banks.

The caddisflies, or order Trichoptera, are a group of insects with aquatic larvae and terrestrial adults. There are approximately 14,500 described species, most of which can be divided into the suborders Integripalpia and Annulipalpia on the basis of the adult mouthparts.

The caddisflies, or Trichoptera, are one of the holometabolous orders of insects for which eggs, larvae, and pupae are especially abundant and diverse in freshwater while adults are generally aerial and terrestrial.

Trichoptera is a rather large holometabolous order. Larvae and pupae of all species are aquatic, with one or two exceptions, and represent an important part of the insect fauna of most streams. About 1400 species are known from North America.

All members of the order Trichoptera are aquatic as in the stages of larvae and pupae, while adults are terrestrial. Some species are still known only as adults, while their larval stages have not been described yet.

Trichoptera is an order of moth-like, holometabolous insects, known commonly as caddisflies (or caddis flies), with aquatic, silk-spinning, caterpillar-like larva and adults that have long antennae and four, large, hair-covered wings that typically are …

Jan 1, 2009 · Trichoptera, or caddisflies, are holometabolous insects closely related to Lepidoptera, or moths. However, unlike most moths, their eggs, larvae, and pupae are usually found in or very near freshwater, and adults are aerial, usually not …

Order Trichoptera. COMMON NAME: CADDISFLIES. The caddisflies are medium-sized, four-winged, moth-like insects having long, slender antennae. They have chewing mouthparts, but the adults probably do not feed. Metamorphosis is complete, the life stages being the egg, larva, pupa, and adult.

Informational resource on the caddisflies of the United States and Canada, with distributional checklist of species.

Feb 12, 2012 · Trichoptera Literature Database (TLD) is a collaborative effort to provide online access to a bibliography of world Trichoptera literature, including access to PDF files of historically important, rare, or out-of-print older works as well as more current literature for caddisflies.

The Trichoptera, or Caddisflies, are an order of insects, somewhat related to moths, and of which there are just under 200 species in the British Isles. The name means 'hairy-winged', and indeed they differ from moths in having hairs rather than scales …

Trichoptera are a cosmopolitan group (though absent from Antarctica), and appear to have evolved in temperate parts of the world, rather than the tropics, with the highest species diversity in the Oriental region.

A caddisfly (or caddis fly) is any insect in the order Trichoptera. An insect order is a very large category, larger even than a family. Three other insect orders, for example, are the “ants, bees, and wasps”; the “butterflies and moths”; and the “grasshoppers, katydids, crickets, and …

Trichoptera: caddisflies. Characteristics Caddisflies are related to Lepidoptera and resemble small hairy moths, but their wings are covered in dense hairs rather than scales and they lack the typical curled proboscis of most moths and butterflies. They are mostly dull-coloured and range in size from 2-40 millimetres in body length.

Apr 19, 2020 · Trichoptera are described as medium-sized insects with setaceous (bristle like) and often long antennae. They have membranous, generally hairy wings which are held tent-like over the body when at rest – most are weak fliers. They …

The Trichoptera is an order of insects, also known as caddisflies, sedge-flies, or rail flies. They are usually identified by the setae (hairs) that cover their entire bodies, including their wings.

Trichoptera, or caddisflies, comprise the most diverse insect order whose members are exclusively aquatic. Only aquatic Diptera outnumber them in species and ecological diversity.
