Geographica." physical characteristics Larvae are small, up to 0.36 in (9 mm) in length. Integripalpia are common, and cosmopolitan. "Caddisflies: Trichoptera feed on algae and others pierce plants sucking out the phloem Since many species are found only in a small region, the slightest disturbance in their environment may have a devastating effect on the entire population. Integripalpia are the most speciose trichopteran suborder with xxx species, according to the Trichoptera World Checklist (Morse, 2010). With only their head, thorax, and legs sticking out of the case, the larvae drag themselves across the stream bottom to search for food. Grzimek's Student Animal Life Resource. such as sand or plant debris to provide protection and camouflage. mate during flight and one female can lay up to several hundred 13: 5. Adult takes place underwater within the larval case or in a pupal case Proceedings of the Entomological Society of Washington publishes research in entomology such as systematics, taxonomy, biology, ecology, and morphology. Caddisflies are ready to mate as soon as they emerge from their cocoons. They use bits of leaves, twigs, or small gravel to construct portable cases. 13,000 species worldwide, 1100 in Europe Trichoptera larvae.

Fly fishermen make all sorts of lures that mimic the various stages of caddisfly development and use them instead of bait to catch fish. Larvae collected in the southeast region of Brazil possibly belong to Alterosa because they possess characteristics that distinguish them from the two known Neotropical genera in this region. The evolution of the group to one with fully aquatic larvae seems to have taken place sometime during the Triassic. The antennae are very long.

In other species, males gather in swarms and engage in dances to attract females. Campodeiform (elongated and flattened) larvae are found in aquatic habitats and are either free-living or net forming, whereas eruciform (caterpillar-like) larvae are case-bearing. The larvae occur in ponds, lakes, stream, and other bodies of water. They therefore have poor dispersal capabilities are rarely move far from the place they were born. The cases become narrow at the Several species can live together in a stream or river because each occupies habitats within the water that do not overlap. Though many school children are familiar with the case-bearing larva – which are common residents of most areas of fresh water – few are as equally acquainted with the adult or imago. Tree of Life Web Project. All caddisflies are vulnerable to changes in water quality. oxygen, temperature, chemicals and particulate matter in the water found near water. A few species of caddisflies are considered pests. However, there are characteristics that also separate these groups.

Other species simply lay their eggs on plants hanging over the water. The adults are often attracted by the thousands to lights, clogging air conditioners with their bodies. Key fish food. They remain close by all the larval stage. Their heads are distinct and hard with strong jaws. LaFontaine, G. Caddisflies. Ancestral Mecoptera (scorpionflies) probably gave rise to the Neuroptera (lacewings), Trichoptera (caddisflies), and Lepidoptera (moths, butterflies). The legs are long, slender, and have scattered spines. habitat On stones The name means 'hairy-winged', and indeed they differ from moths in having hairs rather than scales on their wings, amongst other differences. Depending on the species, the larvae eat bits of plant materials on the bottom or in the water, living plants, living and dead animals, or most or all of the above. b. Oxyethira sp. The trichoptera insect order consists of numerous species of moth-like insects called caddisflies that grow to be less than one inch long. Depending on the species, larvae may be herbivorous, carnivorous, or omnivorous. The long, soft ten-segmented abdomen is slender or plump and sometimes has gills along the sides. "Trichoptera. The movement of the larvae inside the case helps to draw a steady current of water past the gills enabling a constant supply of oxygen. the larval stage and the adults are generally short lived. Larvae construct tubular cases, made from a wide variety of materials, and in a wide variety of architechture. Compound eyes have multiple lenses; simple eyes have only one. The adults are usually small and drab with four moth-like wings and long, slender antennae. They spend their days hiding in moist, cool habitats and are often found on vegetation growing along river banks. However, the two groups are now thought to represent different evolutionary lines. Psychomyiidae have a hatchet shaped trochantin (Fig. Like all insects, the body of grasshoppers…, Skip to main content have a wide variety of feeding methods and diets. Toronto and Buffalo, New York: University of Toronto Press, 1996. Larval cases are made of plant material, sand, stones or other debris. This is how they earned the common name, “net spinners”. These hold on to the case. Predatory species wander about freely in the environment hunting for food animals, but many plant-feeding species live in protective cases built from pebbles, sand, or bits of vegetation from the bottom and held together with silk. capture prey. Willows are a diverse group of about 300 species of woody angiosperm plants in the genus Salix, family Salicaceae.

Bug City. In flight, the hind wings are coupled to the front wings by specially curved hairs. For example, drumming sounds may drive some species to mate, but in others the same sounds are part of a defensive behavior that signals an attack.

Geographic range:This species lives in Europe and western Russia. New York: The Lyons Press, 1994. When the larvae hatch from eggs, they fall into the water and search for the sponges. The order Trichoptera (or caddisflies) are a group of insects with aquatic larvae and terrestrial adults. They are very particular about water temperature and speed, dissolved minerals and pollutants, as well as the amount of sunlight. They live in water, and thus must construct homes to shield themselves from enemies. They are folded like a roof over the body when at rest. Aquatic Insects. This feature combined with branched gills running along ventral surface of their abdomens differentiate the hydropsychids from all other trichopterans. Main characteristics of Caddisflies BMC Evol. Larvae Trichoptera larvae look somewhat like caterpillars. larvae aquatic with thoracic, abdominal, and anal gills.chewing mouthparts. Net-spinners build a fixed silken retreat on the rocky bottoms of swift streams with a weblike net to capture bits of plants and animals floating in the water. When the larva is fully grown, it leaves the water to spin a cocoon and pupate. Then, copy and paste the text into your bibliography or works cited list. The mission of Trichoptera Nearctica is to serve as an informational resource on Trichoptera and to provide up-to-date information on the taxonomy and geographic distribution for all species of Trichoptera known to occur in the Nearctic region, North of Mexico. The larvae have 6 legs, but also 2 terminal prolegs ending in hooks. Larvae aquatic, apneustic (no open spiracles), respiration epidermal, often by filamentous abdominal gills.

Integripalpia are common, and cosmopolitan. Because of their sensitivity to water pollution, the presence or absence of caddisfly larvae is used as an indicator of water quality. Larvae build stationary retreats of silk, detritus and rock fragments. in a casing made from silk that they cover in various materials and well developed legs. In more mature larvae, the segment of the anal proleg closest to the body is longer than the segment furthest from the body (Fig. Pupation They pupate inside the case while they are still underwater.
