Ochrotrichia is a large genus of microcaddisflies. All are Nearctic or Neotropical in distribution apart from Ochrotrichia verbekei , recorded from the Democratic Republic of the Congo.
The caddisflies 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.
The web-footed tenrec, Malagasy otter shrew, or aquatic tenrec is the only known semiaquatic tenrec, and is found in eastern Madagascar, especially in and around Ranomafana National Park. It grows to between 25 and 39 cm, and was once thought to be extinct. It feeds on crabs, aquatic insects, and crayfish. The population is considered vulnerable. It was formerly placed in the monotypic genus Limnogale, but has been moved to Microgale based on molecular data showing it to be deeply nested within the latter.
The family Leptoceridae are a family of caddisflies often called "long-horned caddisflies" or "silverhorns". Leptoceridae is the second largest family of caddisflies with over 1850 species in approximately 68 genera. The main identifying feature of most Leptoceridae is that their antennae are much longer than those of other caddisflies. There is one genus with relatively short antennae (Ceraclea), but it is easily identified by the pair of dark curved lines on the mesonotum.
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 and Trichoptera (caddisflies). In 2017, a third fossil order was added to the group, the Tarachoptera.
The Hydroptilidae are a large family of caddisflies (Trichoptera) with a 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 5 mm (0.20 in) 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 Purse-shaped case, either portable or stuck to the substrate, in which the larva finishes growth and pupates.
The Hydropsychidae are a family-level taxon consisting of net-spinning caddisflies. Hydropsychids are common among much of the world's streams, and a few species occupy the shorelines of freshwater lakes. Larvae of the hydropsychids construct nets at the open ends of their dwellings which are responsible for their "net-spinning caddisfly" common name.
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 Xiphocentronidae are a family of caddisflies. It has previously been treated as a subfamily of Psychomyiidae, and has a broad distribution, including parts of Asia, Central Africa and the Americas. It contains nine genera, in three subfamilies: Since the subgenus Cnodocentron (Caenocentron) was elevated to genus level; and the Cretaceous fossil genus Palerasnitsynus was moved from Psychomyiidae to a new subfamily within Xiphocentronidae.
Dipseudopsidae is a family of caddisflies in the order Trichoptera. There are about 6 genera and at least 110 described species in Dipseudopsidae.
Culoptila is a genus of caddisflies found primarily in Central America as well as the United States.
Stolokrosuchus is an extinct genus of crocodyliforms that lived during the Early Cretaceous. Its fossils, including a skull with a long thin snout and bony knobs on the prefrontal, have been found in Niger. Stolokrosuchus was described in 2000 by Hans Larsson and Boubacar Gado. The type species is S. lapparenti. They initially described it as related to Peirosauridae, if not a member of that family. One study has shown it to be related to Elosuchus. However, more recent works usually find Stolokrosuchus to be one of the basalmost neosuchian, only distantly related to the elosuchid or pholidosaurid, Elosuchus. It was a semiaquatic crocodylomorph.
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.
Lepidostoma is a genus of bizarre caddisflies in the family Lepidostomatidae. There are more than 150 described species in Lepidostoma.
Chimarra is a genus of little black caddisflies in the family Philopotamidae. There are more than 630 described species in Chimarra.
Hydroptilinae is a subfamily of microcaddisflies in the family Hydroptilidae. There are at least 60 genera and 1,600 described species in Hydroptilinae.
Wormaldia is a genus of fingernet caddisflies in the family Philopotamidae. There are more than 140 described species in Wormaldia. Fossil species have been described from the Late Cretaceous Burmese amber of Myanmar.
Liadotaulius is an extinct genus of caddisflies. It is currently (tentatively) placed in the family Philopotamidae, though it has previously been placed in the extinct families Necrotauliidae and Dysoneuridae.
Antistrophus is a genus of about 10 species of gall wasps. The genus is only known from the Nearctic. Species of Antistrophus induce galls on plant species in four Asteraceae genera: Silphium,Lygodesmia, Chrysothamnus, and Microseris.
Maireana trichoptera is a plant in the Amaranthaceae family, native to all mainland states and territories of Australia except Queensland.
