A.D. Huryn, in Encyclopedia of Inland Waters, 2009. There are no fossil records for either the Aglossata or Heterobathmiina. 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. (2013) presented new records of Notalina roraima from Roraima-tepui and Churí-tepui and described some morphological variation in the male genitalia. 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 immature stages are ubiquitous in freshwaters, but are especially diverse in rivers and streams. Recovery of stream communities following disturbance is rapid in such systems, with predisturbance levels of abundance and biomass being attained in ≤3 months. Although many insect orders are represented among the hyporheos, the larvae of chironomid midges (Figure 1) are particularly abundant. Characteristics Mayflies are small to medium sized insects with an average wingspan up to 15 millimetres. The adults have slender brown bodies. For example, substratum movement during flash floods in desert streams of the southwestern United States may reduce macroinvertebrate biomass by as much as 98%. Ancestral Mecoptera (scorpionflies) probably gave rise to the Neuroptera (lacewings), Trichoptera (caddisflies), and Lepidoptera (moths, butterflies). More than a dozen moth fossils from the Upper Jurassic and Cretaceous are unassignable to a family. Classification is based on traits such as wings and mouthparts. Photos by Alex Huryn. Caddis flies, order Trichoptera, are small flying insects that are probably more closely related to the butterflies and moths (order Lepidoptera) than to true flies (order Diptera). 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. 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. Ralph W. Holzenthal, ... Blanca Ríos-Touma, in Thorp and Covich's Freshwater Invertebrates (Fourth Edition), 2015. The larval mouthparts are adapted for chewing; the adult mouthparts are adapted for feeding on liquids. 35).

The Trichoptera include more species than any of the other primarily aquatic orders of insects. Larva of Lara avara (Coleoptera: Elmidae), a xylophagous (wood feeding) shredder that occurs in headwater streams of northwestern North America. Correct answers: 3 question: Analyze the following statements and select those that correctly reflect the characteristics of archaea. Skalski has raised an interesting point—that some early stem group Lepidoptera may be unrecognized because currently they are assigned to the Trichoptera. The abdomen terminates in hook-bearing prolegs. The effect of climate change and other human impacts on the diversity and distribution of caddisflies is discussed. At the other extreme, discharge may cease completely during droughts with equally significant effects. When collecting immature Trichoptera, Preserve the case in alcohol along with the larva, pupa, or both. (Exceptions are females in the family Mengenillidae. Tomáš Derka, ... José Manuel Tierno de Figueroa, in Biodiversity of Pantepui, 2019. Habitat:The larvae are found on plants growing in shallows close to the river bank, usually at depths of 7.87 to 59.05 inches (0.2 to 1.5 meters). Because of the many similarities that the members of this order share, many species of flies are extremely adaptable and can be found globally in every corner of the earth. When the larva is ready to pupate, the animal attaches the case to a rock or other fixed object in the water. Case-making larvae are mostly detritus or plant feeders. Key to the folding mechanism is the third axillary sclerite and pleural wing-folding muscle. 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. Characteristics Orthopterans have a generally cylindrical body, with elongated hindlegs and musculature adapted for jumping . Most of the time, the males have a large antennae. 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. University of Toronto Press. (2017) published descriptions of four new Atopsyche species (Fig. They also have halteres, which are smaller, modified wings that look like dumbbells that they use to help balance themselves while flying. 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. Thorax: The prothorax is usually reduced. The AES published the Beginner's Guide to Caddis by Ian Wallace in the February 2003 issue of the Bulletin. Therefore the species identification of larvae (Fig. The most fundamental lotic habitats, riffles and pools, are inhabited by distinct insect assemblages. Copyright © 2020 Elsevier B.V. or its licensors or contributors. all the species of Trichoptera are aquatic, except for a few cases. 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. Larger species can be pinned and set in the way Lepidoptera are preserved, but smaller species may be better preserved in a suitable liquid. The antennae are multisegmented and filiform and often as long as the wings. Trichoptera seem to have diversified at temperate as well as at tropical latitudes (Ross, 1967), with the Phryganeidae, Stenopsychidae and Limnephilidae occurring mostly in temperate regions, and other taxa (e.g. 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. Species found in still water are usually easy to rear through to adulthood, but those from running water are more troublesome. Peter S. Cranston, Penny J. Gullan, in Encyclopedia of Insects (Second Edition), 2009. Larva of Tipula abdominalis (Diptera: Tipulidae), a widely distributed and common shredder of leaf detritus that occurs in streams throughout much of North America. Aquatic respiration, osmoregulation, diapause, and other physiological adaptations are reviewed. Inset: Digitally enhanced photo of the venter of the head capsule of a Simulium larva showing details of labral fans used for filter feeding. The aquatic larvae use silk to construct cases in which they reside or to spin silken nets to capture food suspended in the water column. 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 … 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. (A) Filtering net and (B) tubular retreat. Many larvae live in characteristic cases constructed of pebbles, sand grains, twigs, or other materials found in ponds and streams. The order name Trichoptera is derived from Greek (trich = hair; pteron = wing) and refers to the hairy appearance of the wing. Larry Serpa, with permission. Zamora-Muñoz et al. By continuing you agree to the use of cookies. The oldest unequivocal moth, Archeolepis mane, dates to the Lower Jurassic. Examples from the lower Cretaceous represent extinct genera, while those from the Tertiary are assigned to modern genera. Photo: Jessica Lawrence, Eurofins Agroscience Services, Bugwood.org. Hence, although Lepidoptera is the most recently evolved major insect order, its radiation was relatively rapid, paralleling that of the angiosperms, the major lineages having evolved between ca. Morphological and molecular evidence fail to confirm Spicipalpia monophyly, unless at least Hydroptilidae is removed. 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. During periods of high flow, stream substrata may tumble along the stream bed with devastating consequences to insect communities. It is available here as a free download. Humans share over 20 percent of our DNA with Drosophila melanogaster, the fruit fly commonly used to teach genetics in high school science labs. Jerry A. Powell, in Encyclopedia of Insects (Second Edition), 2009. About 15,000 species are known. It includes approximately 15,000 extant species within 49 families and approximately 600 genera (Holzenthal et al., 2011, 2015). Although most of these clearly belong to preglossatan taxa, this is not true of all. Micropterigids have been identified from several amber and sedimentary deposits. Figure 4. ... Trichoptera. If you continue to use this site we'll assume that you're happy with this. 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). Glossatans, including a putative lophocoronid, are well substantiated from the Upper Cretaceous. 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 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. Not surprisingly, most of the modern superfamilial and species diversity appear after the angiosperms began radiating in the early Cretaceous. There are fossils of Triassic age assigned to Trichoptera (caddisflies), the presumed sister group of Lepidoptera, and so branching of the two lineages could have occurred in the early Mesozoic (Fig. Monophyly of a third putative suborder, Spicipalpia, is more contentious. The oldest unambiguous macrolepidopteran fossils are Paleocene. Free living larva construct a shelter for pupation, The larva have six well developed legs, and at the end of the abdomen, a pair of prolegs bearing hooks, which distinguish the order. • males have two hind wings, but instead front wings, they have two, small, knobbed, stalk-like structures. They are brownish yellow in color. We use cookies to help provide and enhance our service and tailor content and ads. All possible relationships between Annulipalpia, Integripalpia, and Spicipalpia have been proposed, often associated with scenarios concerning the evolution of case-making. 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. Among these, two were assigned to Micropterigidae and two to Glossata and Ditrysia, but only one of them, Protolepis, possesses visible mouthpart structures. Order Trichoptera . By 102 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). About 5,000 species in 20 families are known for the order. Trichoptera larvae are aquatic and display a pair of hooklike appendages at the apex of the abdomen. This finding has special significance because phylogenetic reconstructions for the order have an angiosperm-feeding lineage (the Heterobathmiina) branching off prior to the evolution of the Glossata (Fig. The first thing you learned about members of the order Diptera is that they all have one pair of wings which allow them to fly. Photo by Alex Huryn. Proposed internal relationships within the Trichoptera range from stable and well supported, to unstable and anecdotal. (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 8.3E) from eastern Pantepui: Atopsyche (Atopsaura) carmenae, Atopsyche (Atopsaura) cristinae, Atopsyche (Atopsaura) inmae, and Atopsyche (Atopsaura) svitoki. The discharge of streams and rivers can vary greatly in time. In addition to pools and riffles, submerged woody debris – or ‘snags’ – provide an important habitat for insects in larger streams and rivers, particularly those with sandy substrata. 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 oldest unequivocal moth, Archeolepis mane, dates to the Lower Jurassic. Figure 35. Major orders of lotic insects include the Ephemeroptera, Plecoptera, Auyán-tepui, Churí-tepui, Roraima-tepui, Roraima-tepui, Churí-tepui, Auyán-tepui. Most are intolerant of pollution and serve as biological indicators of water quality. Dairy wings (Trichoptera, Wing characteristics) Complete metamorphosis (Hymenoptera, Type of Development) Incomplete metamorphosis (Orthoptera, Type of Development) Flies (Diptera, Examples) True bugs (Hemiptera, Examples) Butterflies, moths (Lepidoptera, Examples) Caddisflies (Trichoptera, Examples) Download jpg. David L. Wagner, in Encyclopedia of Biodiversity, 2001. Figure 3. Trichoptera, or caddisflies, are an order of aquatic insects occurring around the world in rivers, streams, and lakes. David L. Wagner, in Encyclopedia of Biodiversity (Second Edition), 2013. 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. Trichoptera pupae are of the exarate type, with the antennae, legs, and developing wings free from the body. 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. Immature caddisflies occur in almost every type of freshwater habitat and on every continent except Antarctica; they are often one of the most abundant insect orders in streams and ponds. 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. FIGURE 4.29. Diet:The larvae eat green plants. 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. 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). (2012) and Derka and Zamora-Muñoz (2012) have been published, only two further studies have been added. Snags often support high densities of filter-feeding caddisflies and filter-feeding Diptera such as larval black flies (Simuliidae; Figure 5). Inset shows details of the larva of Hydropsyche. That is, the fundamental clades of Lepidoptera are all represented before the beginning of the Tertiary. The tracheal system is closed, and is associated with tracheal gills on most abdominal segments. 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). 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. Table 8.3. Review of Trichoptera taxa from Pantepui. There are no fossil records for either the Aglossata or Heterobathmiina. Feeding: Collectors/filterers – omnivorous larvae feed on algae, detritus and small invertebrates that get caught in the net. The pupa is also aquatic, enclosed in a retreat often made of silk, and possesses functional mandibles to aid in emergence from the sealed case. Introduction. John C. Morse, in Encyclopedia of Insects (Second Edition), 2009. There are five putative Lepidopteran fossils from the Triassic; these cannot be assigned to the order with certainty. Major orders of lotic insects include the Ephemeroptera, Plecoptera, Trichoptera, and Diptera. That interpretation has been questioned, the structures possibly being maxillary palpi, and therefore the fossil may represent an extinct lineage of Aglossata. Current velocity is a particularly important factor because many stream insects depend on water currents to obtain food. 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. R.W. Amphiesmenoptera (Trichoptera+Lepidoptera) is now unchallenged, despite earlier suggestions that Trichoptera arose from within Lepidoptera. Caddisfly - Caddisfly - Evolution and paleontology: The caddisflies were long classified in the order Neuroptera. Photo by Alex Huryn. Immature and adult Trichoptera. Glossatans, including a putative lophocoronid, are well substantiated from the Upper Cretaceous. 1516149 | Learning to See, Seeing to Learn A Sociotechnical System Supporting Taxonomic Identification Activities in Volunteer-Based Water Quality Biomonitoring Angiosperm radiation spans 130–95 mya from the earliest recognized occurrence of pollen to the time when angiosperms became the dominant vegetation. Trichopteran adults are characterized by four wings that bear hairs on the membrane or prominent veins, or both. 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. Inset figure redrawn from Wiggins (1977) Larvae of the North American caddisfly genera. The literature on general aspects of life history, ecology and behavior, such as adult emergence, mating behavior, egg laying, predation, construction behavior, food and feeding, drift, and production is reviewed. Minute wing or wingless insects. Group of Prosimulium (Diptera: Simuliidae) larvae in the process of filtering seston from a stream. Because of their diversity and density in most clean, freshwater ecosystems, the significance of caddisflies for processing nutrients and transferring energy is often great. Insects in reproductive diapause are unable to successfully reproduce until a specific environmental cue (e.g., changes in day length, humidity levels, or temperature thresholds) that stimulates physiological processes, such as egg production and maturation, occurs. 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. Some caddisfly larvae do not make cases but instead spin silken webs, which are used to capture food drifting in the stream. The abdominal hooks are used to drag the case about as the larva feeds. However, insects are usually present in significant numbers only for distances of 20 cm or less from the stream bottom. Scales: Scales cover the external surface of the body and appendages. Top. Characteristics of Coleoptera Definition Pair of hardened wings covering top of body and meeting in straight line down the back; membranous pair of wings covered by wing sheaths when insect is at rest; chewing mouthparts 1516149 | Learning to See, Seeing to Learn A Sociotechnical System Supporting Taxonomic Identification Activities in Volunteer-Based Water Quality Biomonitoring 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. The head and thorax are also usually hairy. Head: The head has large compound eyes and, if mouthparts are present, they are almost always a drinking straw-like proboscis. Its larvae feed on bat dung. Three superfamilies have been distinguished, which include five groups based on case-building behaviour. Bottom. Skalski has suggested the possibility that some early stem group lepidopteran fossils may be unrecognized because they have been erroneously assigned to the Trichoptera. This high species diversity is correlated with an unusual broad range of ecological specialization. Two new Helicopsyche species, the first one from Roraima-tepui and the second one from Auyán-tepui and Churí-tepui, are currently undergoing description. The most enigmatic macrolepidopteran fossil is the noctuid egg reported by Gall and Tiffney from the Upper Cretaceous (75 mya). Characteristics. Net-spinning caddisfly larvae (order Trichoptera, family Hydropsychidae). In flight, the hind wings are coupled to the front wings by specially curved hairs. • short antennae comprised of 10 or fewer segments • … Adult caddisflies are weak, usually crepuscular (dawn or dusk) fliers. 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. Filtering net and retreat of Hydropsyche betteni (Trichoptera: Hydropsychidae). Moniliform antennae with 9 segments. More than a dozen moth fossils from the Upper Jurassic and Cretaceous are unassignable to a family. 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. 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. Mandibles are dectitious in most families, usually cross each other apically, and point forward (Figure 4(b)). 140 and 90 mya. Not surprisingly, most of the modern superfamilial and species diversity appears after the angiosperms began radiating in the early Cretaceous. Examples from the lower Cretaceous represent extinct genera, whereas those from the Tertiary are assigned to modern genera. The earliest fossil recognized as lepidopteran is a small-scaled wing from the Lower Jurassic of Dorset, England. 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… The abdomen bears remnants of the larval gills and has characteristic paired hook plates dorsally that aid the pupa in exiting the pupal shelter. Wings: Two pairs of wings are present in almost all taxa. Characteristics and Facts about Flies (Diptera) - Insects. 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. 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. Four genera were described from Upper Jurassic tuffites from Russia. 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. The name means 'hairy-winged', and indeed they differ from moths in having hairs rather than scales on their wings, amongst other differences. 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. 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. Others make stationary retreats of silk for similar purposes or to serve as food-gathering structures. The hyporheos – the fauna inhabiting the hyporheic zone – may occur many meters below or adjacent to the stream channel. However, the two groups are now thought to represent different evolutionary lines. You can often identify an insect in this order just by the wing shape and color. macronematine Hydropsychidae) occurring mostly in warmer climates. Figure 5. The adults of most species have atrophied (wasted away) mouthparts and feed is restricted to sucking nectar and other plant juices. The wings are clothed with setae and held rooflike over the back when the insect is at rest. 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. Geographic range:This species lives in Europe and western Russia. 28. of 29. While most of these clearly belong to preglossatan taxa, this is not true of all. Grant No. Phylogenetic hypothesis of major lepidopteran lineages superimposed on the geologic time scale, with fossil occurrences indicated. 8.3F), Philopotamidae, Polycentropodidae, and Sericostomatidae belonging to 12 genera have been recorded (Table 8.3). The abdomen ends in a pair of anal processes. Adults can also be found by using a sweep net through suitable vegetation, or by searching structures near water. Facts about Bruce Lee (Lee Jun Fan) Characteristics and Facts about Flies (Diptera) - Insects ... On the surface of each of fly’s wing, there are tiny hairs used to detect changes in air pressure during … Holzenthal, in Encyclopedia of Inland Waters, 2009. 1). The compound eyes are large, and there are two or three ocelli. Micropterigids have been identified from several amber and sedimentary deposits. Neopterous insects primitively have the ability to fold the wings back over their abdomen, using special structures at the base of their wings. The variety of feeding strategies employed by caddisflies is as great as for the highly diverse freshwater Diptera, or true flies. Labandeira et al. Physical characteristics:The larvae of this species measure 0.34 to 0.52 inches (8.5 to 13.0 millimeters) in length. They are generally found during the day resting on vegetation, bridges, or other objects near ponds and streams. Trichoptera: caddisflies. Minor orders include the Odonata, Megaloptera, and Coleoptera. Because comprehensive reviews by Aubrecht et al. This chapter discusses the trichoptera (Caddiflies), holometabolous insects closely related to Lepidoptera, or moths. Three superfamilies have been distinguished, which … The adults, with the body and wings covered with fine hairs, are crepuscular and resemble small moths.
