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. 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 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 wings. They are closely related to the Lepidoptera which have scales on their wings; the two orders together form the superorder Amphiesmenoptera.
Empididae is a family of flies with over 3,000 described species occurring worldwide in all the biogeographic realms but the majority are found in the Holarctic. They are mainly predatory flies like most of their relatives in the Empidoidea, and exhibit a wide range of forms but are generally small to medium-sized, non-metallic and rather bristly.
Helicopsychidae are a family of Trichoptera. The name refers to the helix shaped larval cases and they should not be confused with Limnephilidae which sometimes inhabit the snail shells. Their shells range from 6–8 millimetres (0.24–0.31 in) and are crafted from mineral grains. Their typical habitat is in slow-flowing water in ditches. Helicopsychidae larvae have a comb-like anal hook. Helicopsychidae is divided into two extant genera, Rakiura and Helicopsyche, and two fossil genera Electrohelicopsyche and Palaeohelicopsyche. The family contains more than 270 species and are present on all major faunal regions.
The Ecnomidae are a family of caddisflies comprising 9 genera with a total of 375 species.
The Psychomyiidae are a family of tube-making caddisflies. Members of this family are typically very similar to polycentropodids, most of them can be differentiated by the spur formula is 2-4-4, thyridial cell short, absence of the forewing fork I, and hindwing forks I and IV. Male genitalia has elongate preanal appendages, and reduced tergum IX. The larvae differ by the submental sclerites separated, foretrochantin broad, and the pupal mandible apex whip-like. Larvae construct long silken galleries.
The Glossosomatidae are a family of the class Insecta and order Trichoptera.The family contains 23 genera in three subfamilies. In the US alone, there are 76 spp. in 6 different genera.
Rakiura is a genus of Trichoptera (caddisfly). The genus contains only one species, Rakiura vernale, which is endemic to New Zealand. Rakiura vernale represents the most basal taxon within the Helicopsychidae.
The Ibaliidae are a small family of hymenopteran superfamily Cynipoidea. Ibaliidae differ from most of the cynipoids by the larvae being parasitoids on other wasp larvae in the group Siricidae. The Ibaliidae comprise three extant genera of fairly large wasps, with a total of 20 species, and is a sister group to the rest of the cynipoids except the small subfamily Austrocynipidae.
Andogyrus is a subgenus of Macrogyrus, a genus of beetles in the family Gyrinidae. It was formerly considered a distinct genus, until a phylogenetic study in 2017 downgraded it in rank to a subgenus. It contains the following species:
The Dinidoridae are a small family of insects comprising about a hundred species in sixteen genera in the Hemipteran suborder Heteroptera, the "true bugs". As a group the family does not have any common name. Until the late 19th century they were generally regarded as a subfamily of the Pentatomidae.
Leiodes punctostriata is a species of round fungus beetle in the family Leiodidae. It is found in North America.
Ceraclea is a genus of long-horned caddisflies in the family Leptoceridae. There are more than 140 described species in Ceraclea.
Leiodes appalachiana is a species of round fungus beetle in the family Leiodidae. It is found in North America.
Leiodes rufipes is a species of round fungus beetle in the family Leiodidae. It is found in Europe and Northern Asia and North America.
Leiodes assimilis is a species of round fungus beetle in the family Leiodidae. It is found in North America.
Leiodes horni is a species of round fungus beetle in the family Leiodidae. It is found in North America.
Leiodes puncticollis is a species of round fungus beetle in the family Leiodidae. It is found in Europe and Northern Asia and North America.
Leiodes neglecta is a species of round fungus beetle in the family Leiodidae. It is found in North America.
Anisocentropus krampus is a species of caddisfly in the family Calamoceratidae. It was described in 1994 by Austrian entomologist Hans Malicky and found in New Britain.
Tiphia davidrajui is a species of wasp belonging to the family Tiphiidae, subfamily Tiphiinae.The species is named after a naturalist from Kerala Mr. David V. Raju.
