Trichoptera
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. Integripalpian larvae construct a portable casing to protect themselves as they move around looking for food, while annulipalpian larvae make themselves a fixed retreat in which they remain, waiting for food to come to them. The affinities of the small third suborder Spicipalpia are unclear, and Molecular phylogenetics, molecular analysis suggests it may not be monophyletic. Also called sedge-flies or rail-flies, the adults are small moth-like insects with two pairs of hairy membranous insect wing, wings. They are closely related to the Lepidoptera (moths and butterflies) which have scales on their wings; the two orders together form the superorder Amphiesmenoptera. The aquatic larvae are found in a wide variety o ...

Hydroptiloidea
The Hydroptilidae are a large family of caddisflies (Trichoptera) with a cosmopolitan distribution, worldwide distribution. They are commonly known as microcaddisflies or purse-case caddisflies, in reference to two characteristic traits of this family: Hydroptilidae are much smaller than other caddisflies, rarely exceeding in length. Their larvae do not build a protective case until the final instar of their growth. At that time however, they build a typically Coin purse, Purse-shaped case, either portable or stuck to the Substrate (biology), substrate, in which the larva finishes growth and pupates. Systematics and taxonomy Their systematics, systematic placement among the caddisflies is still disputed. They are traditionally placed in the suborder Spicipalpia, which do not seem to be a natural monophyletic group, but rather an evolutionary grade of moderately advanced caddisflies. Some authors downrank the Spicipalpia to a Taxonomic rank, superfamily of the more basal (evoluti ...

Lepidoptera
Lepidoptera ( ) or lepidopterans is an order (biology), order of winged insects which includes butterflies and moths. About 180,000 species of the Lepidoptera have been described, representing 10% of the total described species of living organisms, making it the second largest insect order (behind Coleoptera) with 126 family (biology), families and 46 Taxonomic rank, superfamilies, and one of the most widespread and widely recognizable insect orders in the world. Lepidopteran species are characterized by more than three derived features. The most apparent is the presence of scale (anatomy), scales that cover the torso, bodies, large triangular Insect wing, wings, and a proboscis for siphoning nectars. The scales are modified, flattened "hairs", and give butterflies and moths their wide variety of colors and patterns. Almost all species have some form of membranous wings, except for a few that have reduced wings or are wingless. Mating and the laying of eggs is normally performe ...

Insect Wing
Insect wings are adult outgrowths of the insect exoskeleton that enable insect flight, insects to fly. They are found on the second and third Thorax (insect anatomy), thoracic segments (the mesothorax and metathorax), and the two pairs are often referred to as the forewings and hindwings, respectively, though a few insects lack hindwings, even rudiments. The wings are strengthened by a number of longitudinal veins, which often have cross-connections that form closed "cells" in the membrane (extreme examples include the Odonata, dragonflies and Neuroptera, lacewings). The patterns resulting from the fusion and cross-connection of the wing veins are often diagnostic for different evolutionary lineages and can be used for identification to the family (biology), family or even genus level in many order (biology), orders of insects. Physically, some insects move their flight muscles directly, others indirectly. In insects with direct flight, the wing muscles directly attach to the win ...

Helicopsyche
''Helicopsyche'' is a genus of Trichoptera, the caddisflies. ''Helicopsyche'' contains more than 230 species and are represented on all major faunal regions with highest diversity in tropical and sub-tropical regions. The genus was first described by Siebold, 1856. The abundance and wide distribution of the genus makes it important to fly fishing anglers, who know it as the "Speckled Peter". Diagnosis Larva The case is dextrally coiled, with coils usually completely fused. Head is oval in dorsal view and smooth except for long setae and lateral carina. In lateral view the head has a trianguloid shape with the dorsal margin straight or slightly concave. Pronotum is strongly sclerotized while meso-and metantoum are weakly sclerotized. Anal claw with a single row of comb shaped hooks. Abdominal gills either are present or absent. Adult The maxillary palps are 2-, 3-, or 4-jointed. Antennae as long as fore wing or two times longer than fore wing length. Cephalic warts variable. ...

Annulipalpia
The Annulipalpia, also known as the "fixed-retreat makers", are a suborder of Trichoptera 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 ..., the caddisflies.Glenn B. Wiggins, ''Larvae of the North American Caddisfly Genera (Trichoptera)'', 2nd. ed. (Toronto: University Press, 1996), p. 117 The name of the suborder refers to the flexible terminal segment of the adult maxillary palps, which often has many tiny rings. The larvae construct fixed retreats in freshwater aquatic environments in which they remain stationary, waiting for food to come to them. Members of the Psychomyiidae, Ecnomidae and Xiphocentronidae families construct simple tubes of sand and other particles held together by silk and anchored to the bottom, and feed on the accumulations of silt formed when suspended m ...

Spicipalpia
The Spicipalpia are a suborder of Trichoptera, the caddisflies. The four families included in this suborder all have the character of pointed maxillary palps in the adults. The larvae of the different families have varying lifestyles, from free-living to case-making, but all construct cases in their final larval instar An instar (, from the Latin '' īnstar'' 'form, likeness') is a developmental stage of arthropods, such as insects, which occurs between each moult (''ecdysis'') until sexual maturity is reached. Arthropods must shed the exoskeleton in order to ... for pupation or at an earlier instar as a precocial pupation behavior. Although recognized under some phylogenies, molecular analysis has shown this group is likely not monophyletic. External linksTree Of Life Trichoptera Page Insect suborders {{Trichoptera-stub ...

Amphiesmenoptera
Amphiesmenoptera is an insect superorder, established by S. G. Kiriakoff, but often credited to Willi Hennig in his revision of insect taxonomy for two sister orders: Lepidoptera (butterflies and moths) and Trichoptera (caddisflies). In 2017, a third fossil order was added to the group, the Tarachoptera. Trichoptera and Lepidoptera share a number of derived characters ( synapomorphies) which demonstrate their common descent: * Females, rather than males, are heterogametic (i.e. their sex chromosomes differ). * Dense setae are present in the wings (modified into scales in Lepidoptera). * There is a particular venation pattern on the forewings (the double-looped anal veins). * Larvae have mouth structures and glands to make and manipulate silk. Thus, these two extant orders are sisters, with Tarachoptera basal to both groups. Amphiesmenoptera probably evolved in the Jurassic. Lepidoptera differ from the Trichoptera in several features, including wing venation, form of the ...

Hubert Duprat
Hubert Duprat is a French artist known for his unusual work, an artistic intersection between caddisfly larvae and gold, opal, turquoise and other precious stones. Caddisfly larvae live in fresh water and naturally construct elaborate protective tubes for themselves from materials found in their environment. Under natural conditions they use the objects found in their stream bed homes such as pieces of wood, fragments of fish bone or crustacean shell, grains of sand, plant debris and small stones. The tubes serve various purposes; the stones are used to increase traction in fast-moving streams, they serve as disguise for the soft-bodied insect and the spiky bits make the tube and thus, the fly larva, more difficult for predators to swallow. Duprat, born in 1957, began his work with caddisfly larvae in the early 1980s. He collects the larvae from their normal environments and he takes them to his studio. There he gently removes their own natural cases and puts the larvae in tank ...
