trichoptera wing characteristics

Their forewings are hairy and from this characteristic comes the name of the order: trikhos is Greek for hairy and pteron means wing. Adult caddisflies are weak, usually crepuscular (dawn or dusk) fliers. Therefore the species identification of larvae (Fig. Figure 3. The conditions imposed by such normal extremes in discharge are often referred to as the natural disturbance regime, which is a fundamental determinant of the structure of stream communities. For example, substratum movement during flash floods in desert streams of the southwestern United States may reduce macroinvertebrate biomass by as much as 98%. The adults, with the body and wings covered with fine hairs, are crepuscular and resemble small moths. 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.

This high species diversity is correlated with an unusual broad range of ecological specialization. Unlike most moths, their eggs, larvae, and pupae are usually found in or very near freshwater, and adults are aerial, usually not far from their aquatic habitats. More than a dozen moth fossils from the Upper Jurassic and Cretaceous are unassignable to a family. This chapter provides an overview of the geographical, morphological, and ecological diversity of caddisflies. At rest the wings are held tent-like over the abdomen. Species found in still water are usually easy to rear through to adulthood, but those from running water are more troublesome. (Coleoptera, Wing characteristics) B. hindwings reduced to stabilizers (Diptera, Wing characteristics) C. wings have scales (Lepidoptera, Wing characteristics) D. hairy wings (Trichoptera, Wing characteristics) E. complete metamorphosis (Hymenoptera, Type of Development) F. incomplete metamorphosis (Orthoptera, Type of Development) G. flies All insects have a three-part body plan consisting of a head, thorax, and abdomen; three pairs of walking legs; and one or two pairs of wings. The name means 'hairy-winged', and indeed they differ from moths in having hairs rather than scales on their wings, amongst other differences. Photos by Alex Huryn. R.W. Dipterans of Interest . Inset shows details of the larva of Hydropsyche. (2017) published descriptions of four new Atopsyche species (Fig. Peter S. Cranston, Penny J. Gullan, in Encyclopedia of Insects (Second Edition), 2009. Group of Prosimulium (Diptera: Simuliidae) larvae in the process of filtering seston from a stream. The strategies used by insects specializing in such ‘temporary’ habitats are diverse and usually include extremely rapid larval development followed by a resting stage, such as desiccation-resistant eggs or pupae, or terrestrial adults in reproductive diapause. Larvae of many species use silk to construct portable cases of various shapes and materials to serve as physical protection, camouflage, or aids in respiration. In the Neotropics, about 3262 valid species in 25 families and 155 extant genera have been currently recognized (Holzenthal and Calor, 2017). Its larvae feed on bat dung. Thorax: The prothorax is usually reduced. That interpretation has been questioned, the structures possibly being maxillary palpi, and therefore the fossil may represent an extinct lineage of Aglossata. The recognition of this is important to understanding spatial patterns of insect diversity in streams. For collecting the adults, other than those attracted by light, a net is needed, whilst a pond net is used for collecting the early stages in water. While the fossil record of the Trichoptera, the sister group to the Lepidoptera, is adequate and dates into the Permian, the record for lepidopterans is meager, especially for Mesozoic-aged fossils, when the basal lineages were diversifying. The representation of insect taxa in temporary aquatic habitats is surprisingly broad, with the Ephemeroptera, Odonata (Lestidae), Hemiptera, Diptera (Culicidae, Chironomidae), Trichoptera, and Coleoptera probably the most commonly encountered. Figure 35. Three superfamilies have been distinguished, which … 3), their presence in the Cretaceous would push back the origin of virtually all lepidopteran higher taxa. Amphiesmenoptera (Trichoptera+Lepidoptera) is now unchallenged, despite earlier suggestions that Trichoptera arose from within Lepidoptera. John C. Morse, in Encyclopedia of Insects (Second Edition), 2009. However, insects are usually present in significant numbers only for distances of 20 cm or less from the stream bottom. David L. Wagner, in Encyclopedia of Biodiversity (Second Edition), 2013. Protolepis cuprealata from Upper Jurassic deposits in Kazakhstan appears to have a coiled proboscis, although an alternative interpretation is that the structure in question be an elongate maxillary palpus. Minor orders include the Odonata, Megaloptera, and Coleoptera. Because comprehensive reviews by Aubrecht et al. Defined for the Glossosomatidae, Hydroptilidae, and Rhyacophilidae (and perhaps the Hydrobiosidae), the proposed uniting features are the spiculate apex of the adult maxillary and labial palps, ovoid second segment of maxillary palp, and eversible oviscapt (egg laying appendage). Most species descriptions of South American caddisflies are based only on adults without associated immature stages. It was placed in a separate family, Archaeolepidae, suggested as a sister group to the Micropterigidae, but without characters known that might establish its relationships. The name of the group is derived from the Greek words for twisted (streptos) and wing (pteron) and refers to the peculiar twisted wing of the male's hind-wings while in flight.Representatives of the suborder Mengenillidia generally show more primitive characteristics (fig. The order name Trichoptera is derived from Greek (trich = hair; pteron = wing) and refers to the hairy appearance of the wing. Figure 5. Morphological and molecular evidence fail to confirm Spicipalpia monophyly, unless at least Hydroptilidae is removed. David L. Wagner, in Encyclopedia of Biodiversity, 2001. Water enters the net structure at the top of the photograph and leaves through the net, where seston is captured, and through the tubular retreat where the larva is concealed. 8.3E) from eastern Pantepui: Atopsyche (Atopsaura) carmenae, Atopsyche (Atopsaura) cristinae, Atopsyche (Atopsaura) inmae, and Atopsyche (Atopsaura) svitoki. 8.3E, F, and H) is nearly impossible. 3). Others make stationary retreats of silk for similar purposes or to serve as food-gathering structures. Correct answers: 3 question: Analyze the following statements and select those that correctly reflect the characteristics of archaea. The antennae are very long. It includes approximately 15,000 extant species within 49 families and approximately 600 genera (Holzenthal et al., 2011, 2015). Jerry A. Powell, in Encyclopedia of Insects (Second Edition), 2009. Neopterous insects primitively have the ability to fold the wings back over their abdomen, using special structures at the base of their wings. Bottom. • short antennae comprised of 10 or fewer segments • … The monophyly of the case-making Integripalpia (comprising families Phryganeidae, Limnephilidae, Leptoceridae, Sericostomatidae, and relatives) is supported inter alia by the absence of the m crossvein, hind wings broader than forewings especially in the anal area, female lacking both segment 11 and cerci, and larval character states including the usual complete sclerotization of the mesonotum, hind legs with lateral projection, lateral and mid-dorsal humps on abdominal segment 1, and short and stout anal hooks. However, the two groups are now thought to represent different evolutionary lines. Trichopteran adults are characterized by four wings that bear hairs on the membrane or prominent veins, or both. The wings are haired or less often scaled, and differentiated from all but the earliest lineages of Lepidoptera by the looped anal veins in the fore wing, and absence of a discal cell. The tracheal system is closed, and is associated with tracheal gills on most abdominal segments. Angiosperm radiation spans 130–95 mya from the earliest recognized occurrence of pollen to the time when angiosperms became the dominant vegetation. Perhaps then, it is not surprising that the oldest unequivocal noctuid fossils also date to the Eocene. (2012) and Derka and Zamora-Muñoz (2012) have been published, only two further studies have been added. Classification is based on traits such as wings and mouthparts. There are five putative Lepidopteran fossils from the Triassic; these cannot be assigned to the order with certainty. Some caddisfly larvae do not make cases but instead spin silken webs, which are used to capture food drifting in the stream. Physical characteristics:The larvae of this species measure 0.34 to 0.52 inches (8.5 to 13.0 millimeters) in length. FIGURE 4.29. Altogether, 30 species belonging to eight genera and six families have been published from Pantepui, and unidentified specimens of Calamoceratidae, Helicopsychidae (Fig. Immature and adult Trichoptera.

Copyright © 2020 Elsevier B.V. or its licensors or contributors. Trichoptera pupae are of the exarate type, with the antennae, legs, and developing wings free from the body. Larva of Tipula abdominalis (Diptera: Tipulidae), a widely distributed and common shredder of leaf detritus that occurs in streams throughout much of North America. Glossatans, including a putative lophocoronid, are well substantiated from the Upper Cretaceous. Diet:The larvae eat green plants. Recovery of stream communities following disturbance is rapid in such systems, with predisturbance levels of abundance and biomass being attained in ≤3 months. The oldest unequivocal moth, Archeolepis mane, dates to the Lower Jurassic. Four genera were described from Upper Jurassic tuffites from Russia. Among these, two were assigned to Micropterigidae and two to Glossata and Ditrysia, but only one of them, Protolepis, possesses visible mouthpart structures. Trichoptera are holometabolous; the moth-like adult has reduced mouthparts lacking any proboscis, but with 3–5 segmented maxillary palps and 3-segmented labial palps. There are slight variations in mouthparts betwee… 's (1994) discoveries of mines of Ectoedemia and Stigmella (both Nepticulidae) and a phyllocnistine (Gracillariidae) from Cenomanian deposits (97 mya), which agree in detail with those of modern species from closely related host taxa, are noteworthy in that they demonstrate the antiquity of many mothplant associations. The oldest unambiguous macrolepidopteran fossils are Paleocene. The abdomen bears remnants of the larval gills and has characteristic paired hook plates dorsally that aid the pupa in exiting the pupal shelter. Examples from the lower Cretaceous represent extinct genera, while those from the Tertiary are assigned to modern genera. Adult females in this family have very simple eyes, as well as legs.) The oldest unambiguous macrolepidopteran fossils are Paleocene. The larva is aquatic, has fully developed mouthparts, three pairs of thoracic legs (each with at least five segments), and lacks the ventral prolegs characteristic of lepidopteran larvae. Trichoptera contains about 45 extant families containing some 13,000 described species, with estimates of undescribed (mostly SE Asian) species diversity some four- to fivefold higher. The different caddisfly species are variously sensitive to changes in environmental conditions, such that the diversity of the order is commonly used in part as a measure of pollution. Mandibles are dectitious in most families, usually cross each other apically, and point forward (Figure 4(b)). Leaf-mining families from the Northern Hemisphere have an extensive fossil record that is believed to reflect their ages of origin as well as their relative abundances. The antennae are long and slender and are usually about the length of the anterior wing, but they may be longer than the wingspan. The name means 'hairy-winged', and indeed they differ from moths in having hairs rather than scales on their wings, amongst other differences. The larval mouthparts are adapted for chewing; the adult mouthparts are adapted for feeding on liquids. Mormotomyia hirsute is only known to live in a large crack at the top of Kenya's Ukazzi Hill. Most of the time, the males have a large antennae. During the day, they hide in cool, moist environments such as the vegetation along river banks. Larger species can be pinned and set in the way Lepidoptera are preserved, but smaller species may be better preserved in a suitable liquid. Another well-represented group of fossil moths are the tineoids, which are richly represented in Dominican amber deposits that date from 40 to 15 mya. The effect of climate change and other human impacts on the diversity and distribution of caddisflies is discussed. The adults have slender brown bodies. Finally, methods for collecting, preparing, and observing immature stages and adults for scientific study are presented. About 15,000 species are known. Trichoptera larvae are aquatic and display a pair of hooklike appendages at the apex of the abdomen. A.D. Huryn, in Encyclopedia of Inland Waters, 2009. Table 8.3. Review of Trichoptera taxa from Pantepui. They are brownish yellow in color. Skalski has suggested the possibility that some early stem group lepidopteran fossils may be unrecognized because they have been erroneously assigned to the Trichoptera. Behavior and reproduction:The larvae build cases with long … There are no fossil records for either the Aglossata or Heterobathmiina. Open dots, reliable identifications; shaded dots, questionable assignments. Case-making larvae are mostly detritus or plant feeders. Common Name: Silk Moths Description: Silk moths have thick and hairy bodies with a wing span that can range over six inches.The wings have dark eye spots. Because noctuids are thought to be among the most derived ditrysian superfamilies (Fig. Photo: Jessica Lawrence, Eurofins Agroscience Services, Bugwood.org. The order Trichoptera (caddisflies) is a group of holometabolous insects closely related to butterflies (Lepidoptera). Trichoptera, or caddisflies, are an order of aquatic insects occurring around the world in rivers, streams, and lakes. The compound eyes are large, and there are two or three ocelli. Holzenthal, in Encyclopedia of Inland Waters, 2009. all the species of Trichoptera are aquatic, except for a few cases. ... Trichoptera. By the early Cretaceous there are well preserved Micropterigidae and an incurvariid (Heteroneura) in amber, and by the late Cretaceous several kinds of leaf mines representing modern families and host-plant associations, both heteroneuran (Nepticulidae) and ditrysian (Phyllocnistidae, Gracillariidae), as well as a ditrysian larval head capsule of a free-living form such as Tineidae. Timothy Gibb, in Contemporary Insect Diagnostics, 2015. The thorax is unmodified, but the thoracic legs often have swimming hairs. 1516149 | Learning to See, Seeing to Learn A Sociotechnical System Supporting Taxonomic Identification Activities in Volunteer-Based Water Quality Biomonitoring The hyporheos – the fauna inhabiting the hyporheic zone – may occur many meters below or adjacent to the stream channel. 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. Photo by Alex Huryn. If you continue to use this site we'll assume that you're happy with this. 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. A few species do not build cases or webs but are free-living and predaceous. The wings of Trichoptera are covered with setae, from which the name of the order is derived (from the Greek "trichos"= hair, and "pteron"=wing). Current velocity is a particularly important factor because many stream insects depend on water currents to obtain food. It is available here as a free download. • males have two hind wings, but instead front wings, they have two, small, knobbed, stalk-like structures. Characteristics and Facts about Flies (Diptera) - Insects. Inset figure redrawn from Wiggins (1977) Larvae of the North American caddisfly genera. A photograph of a a caddisfly larvae.Photograph by Aka licensed under Creative Commons. The most enigmatic macrolepidopteran fossil is the noctuid egg reported by Gall and Tiffney from the Upper Cretaceous (75 mya). 140 and 90 mya. Major orders of lotic insects include the Ephemeroptera, Plecoptera, Auyán-tepui, Churí-tepui, Roraima-tepui, Roraima-tepui, Churí-tepui, Auyán-tepui. The variety of feeding strategies employed by caddisflies is as great as for the highly diverse freshwater Diptera, or true flies. Ancestral Mecoptera (scorpionflies) probably gave rise to the Neuroptera (lacewings), Trichoptera (caddisflies), and Lepidoptera (moths, butterflies). The hyporheic zone is a habitat that occurs within the bed of a stream where interstitial water moves by percolation to and from the stream's channel. Another especially well-represented group of fossil moths is made up of the tineoids, which are richly represented in Dominican amber deposits that date from 15 to 40 mya. Order Trichoptera .

José Manuel Tierno de Figueroa, in, Aubrecht et al., 2012; Derka and Zamora-Muñoz, 2012; Zamora-Muñoz et al., 2013, 2017, Encyclopedia of Biodiversity (Second Edition), There are fossils of Triassic age assigned to, Aquatic Insects – Ecology, Feeding, and Life History. While most of these clearly belong to preglossatan taxa, this is not true of all. Characteristics Mayflies are small to medium sized insects with an average wingspan up to 15 millimetres. Web sites to check: Trichoptera on the NCSU General Entomology page Trichoptera on BugGuide 35). The adults of most species have atrophied (wasted away) mouthparts and feed is restricted to sucking nectar and other plant juices. The eggs are normally laid in or near water in a jelly like substance, The females of many species crawl in to the water to lay their eggs, Whilst some larvae are free-living, others construct various different structures for protection and camouflage, Those species which construct a larval case, usually pupate in the case which has been attached to a support. The body and wings are clothed with long silky hairs (setae) -- a distinctive characteristic of the order. During periods of high flow, stream substrata may tumble along the stream bed with devastating consequences to insect communities. Snags often support high densities of filter-feeding caddisflies and filter-feeding Diptera such as larval black flies (Simuliidae; Figure 5). Some taxa (e.g., larvae of hydropsychid caddisflies) occur in riffles because they feed by filtering organic particles from rapidly flowing water that become trapped in their nets (Figure 3), while others (e.g., crane fly larvae; Figure 4) are found in pools because they feed on decomposing leaves that accumulate in these tranquil habitats. The Insect Orders V: Trichoptera and Lepidoptera Trichoptera: The caddisflies Caddisfly adult, left, (University of Minnesota) and larvae, right (University of Iowa) Tricho = hair; ptera = wings; refers to the hair-covered wings of adults. They associated the larvae of two of the species, Atopsyche cristinae and A. inmae, and performed a phylogenetic tree to assess the molecular validity of the species, establish an evolutionary relation among them, and interpret the historical biogeography of tepuis. By 97 mya, modern genera of ditrysians are recognizable, suggesting that early evolution of the order occurred on nonseed plants and gymnosperms during the late Jurassic (Labandeira et al., 1994). All of these groups share the common characteristics of the order Diptera with their similar body and wing structure and complete cycle of metamorphosis. Monophyly of suborder Annulipalpia in its strictest sense, comprising families Hydropsychidae, Polycentropodidae, Philopotamidae, and some close relatives, is well supported by larval and adult morphology —including presence of annulate apical segment of both adult maxillary and larval palp, absence of male phallic parameres, presence of papillae lateral to the female cerci, and in the larva by the presence of elongate anal hooks and reduced abdominal tergite 10. Glossatans, including a putative lophocoronid, are well substantiated from the Upper Cretaceous. This chapter discusses the trichoptera (Caddiflies), holometabolous insects closely related to Lepidoptera, or moths. Figure 4. Head: The head has large compound eyes and, if mouthparts are present, they are almost always a drinking straw-like proboscis. Mayflies can be recognised by the following characteristics: Caddisfly - Caddisfly - Evolution and paleontology: The caddisflies were long classified in the order Neuroptera. 1). The characteristics of the antenna varies, but can be bipectinate or feathery. By definition, sister taxa are of equal age, and thus it is curious that the oldest caddisfly and moth fossils are of such disparate ages. Trichoptera: Sub-Order: Integripalpia: Family: Apataniidae: Common Name: Early Smoky Wing Sedge : Distinguishing Characteristics: Scraper blade usually found on inside of mandibles; If mandible is toothed, then more than 25 setae are present on membranous area … Caddisflies are soft-bodied insects with long, slender antennae and two pairs of membranous wings. Whereas the fossil record of the Trichoptera, the sister group to the Lepidoptera, is adequate and dates into the Permian, the record for lepidopterans is meager, especially for Mesozoic-aged fossils, when the basal lineages were diversifying. Because the oldest documented angiosperms are Lower Cretaceous (and Protolepis is Upper Jurassic), this suggests that either specialized angiosperm-feeding evolved at least twice within the Lepidoptera or that the date for the origin for angiosperms is, in fact, much older. The study of caddisflies in mid-Cretaceous Burmese amber is still in its infancy, it being too early to get more than a preliminary overview of the Tr… (Exceptions are females in the family Mengenillidae. Arguing against Gall and Tiffney's identification is the observation that all present-day noctuids have a thoracic “ear” sensitive to the ultrasonic frequencies emitted by bats and that the oldest bat fossils date back only to the Eocene. The caddisfly suborders Annulipalpia and Integripalpia (Trichoptera) each have evolved a wing coupling apparatus, with at least three systems having evolved within the suborder Annulipalpia. General characteristics: • most adult females are wingless, legless, eyeless, and look much like grubs. They were interpreted as a siphon formed of maxillary galeae, which would imply existence of Glossata, 20–30 mya, prior to the radiation of angiosperm plants during the early Cretaceous. Grant No. The cessation of discharge and the complete evaporation of surface water from streams and wetlands affect community structure by imposing conditions that are too harsh for insect taxa that lack strategies allowing them to persist through dry periods (e.g., desiccation resistance, access to refugia). 8.3H), Hydropsychidae, Hydroptilidae, Leptoceridae, Odontoceridae (Fig. Strepsiptera are obligate parasites of insects, with hosts ranging across 7 orders and 34 families. Although most of these clearly belong to preglossatan taxa, this is not true of all. Larva of Lara avara (Coleoptera: Elmidae), a xylophagous (wood feeding) shredder that occurs in headwater streams of northwestern North America. They also described and illustrated the larva of this species and included information on its habitat. Micropterigids have been identified from several amber and sedimentary deposits. Not surprisingly, most of the modern superfamilial and species diversity appear after the angiosperms began radiating in the early Cretaceous. Although many insect orders are represented among the hyporheos, the larvae of chironomid midges (Figure 1) are particularly abundant. Introduction. General characteristics: • may be winged or wingless • among those with wings, each wing is a slender and rather feathery affair: a thin rod with a comb of fringe-like hairs on either side (one side may have more fringe than the other). Adults can also be found by using a sweep net through suitable vegetation, or by searching structures near water. Micropterigids have been identified from several amber and sedimentary deposits. Not surprisingly, most of the modern superfamilial and species diversity appears after the angiosperms began radiating in the early Cretaceous. Characteristics. In flight, the hind wings are coupled to the front wings by specially curved hairs. Humans share over 20 percent of our DNA with Drosophila melanogaster, the fruit fly commonly used to teach genetics in high school science labs. The immature stages are ubiquitous in freshwaters, but are especially diverse in rivers and streams. Trichoptera are holometabolous; the moth-like adult has reduced mouthparts lacking any proboscis, but with 3–5 segmented maxillary palps and 3-segmented labial palps. Because of their diversity and density in most clean, freshwater ecosystems, the significance of caddisflies for processing nutrients and transferring energy is often great. There are no fossil records for either the Aglossata or Heterobathmiina. You can often identify an insect in this order just by the wing shape and color. The abdomen terminates in hook-bearing prolegs. Such communities are primarily composed of taxa with life-history strategies that enable rapid recolonization.
