My caddisfly predilection is reserved for the larval stages that last for most of the insects one or, less often, two or three year life span. Thats because the most common caddisfly larva is called an aquatic worm or hookworm, and it spends its life infecting freshwaterfish with tapeworms that are then consumed by humans.

MeSH Economics have driven government and personal gain for some time and it has beenimbedded into our culture for centuries. Like moths, most caddisflies undergo complete metamorphosis the immature stages look very different from the winged, adult stage, and the larvae enter a pupal stage before becoming adults. Most species produce one or two generations per year. If it cannot find shade or shelter, such as in the wintertime, the pupal case serves to protect it from freezing until warmer weather comes along. As with most aquatic insects, the animal can appear different depending on its stage of development. Three other insect orders, for example, are the ants, bees, and wasps; the butterflies and moths; and the grasshoppers, katydids, crickets, and cockroaches.

Like ice climbers using crampons, they also have impressive claws that grow right out of their rear ends. The presence of Ca(2+) in the caddisfly larval silk proteins suggest phosphorylated serines could contribute to silk fiber periodic substructure through Ca(2+) crossbridging. [ Source] They can eat up to ten times their body weight per day, making them one of the fastest growing insects on earth. Their name translates to "rock loving," and this preference serves them well in fast-flowing streams. Continually submerged stones and pieces of wood provide the best substrate for growth of algae and periphyton, which the larvae effectively scrap. Brachycentridae (Case-building caddisfly larvae) Larvae continuously clean their nets by picking off inorganic pieces and consuming organic matter. The larvae are a link in the aquatic food chain, bridging the gap between the various organic matterials they eat, and the fish that eat them. Introduction: Caddisflies are closely related to moths (order Lepidoptera), which they are often mistaken for. They use various parts of living or death vegetation such as twigs, stems, leaves, needles or pieces of bark. They then emerge from the cocoon, float to the water's surface or the shore, and finish their transformation to an adult, terrestrial insect.

Habitat: Some species have branched gills or humps on the sides of the body (in order to increase the body surface). However, most caddisflies are herbivores that graze on phytoplankton, shred larger plants and detritus, and catch drifting algae in their nets or leg-hairs. The caddisfly larva lives underwater, and gathers bits of sand, gravel or other small particles to build a protective case for itself out of silk secreted from glands near the rear end. I have seen Neophylax cases made primarily from tiny pieces of broken brick eroded from a construction site.

For whatever reason, my refined taste as an entomologist has developed as a preference for a silk-spinning, case-building aquatic insect. Caddisflies that live on soft sediment often build wide, flattened cases that act like a snowshoe, keeping the insect from sinking. The larva attaches one end of a silk strand to an object and pulls it underwater where it deposits its sifting material, then ties off the other end to a rock or other anchorage so that when the caddisfly swims back up for air, any loose particles are left behind on the now-weighted silk line. I cant tell if this is a more or less effective tactic than the search and destroy approach of their rock loving cousins; Nyctiophylax larvae are certainly slimmer. In general, larvae living in running water use heavier components to increase their overall weight. Thank you Nathan Buckley for your wonderful question. Some caddisflies create a retreat that they attach to a substrate. Most creep along rocks and other submerged objects in the clean waters of streams, rivers, and springs, where the movement of the water increases the oxygen level. Two caddisfly families are distinguished by their complicated silk nets. Fascinating story. Caddisflies that build cases out of organic matter are found in slow parts of flowing waters and shallow areas of lakes and ponds where debris can accumulate, and where the neutrally buoyant case won't be swept away. sharing sensitive information, make sure youre on a federal When the larvae are fully grown and ready to pupate, they fortify the retreats with additional material and seal the entrance.

Larvae do not live in protective cases or retreats, but like other caddisfly larvae, they build protective structures for the pupae.

Shredders/scrapers/collectors larvae mostly feed on periphyton (layer of algae and associated flora and fauna) and pieces of both aquatic and terrestrial vegetation. Major molecular adaptations allowing underwater spinning of an ancestral dry silk appear to have been phosphorylation of serines and the accumulation of basic residues in the silk proteins. They use their sticky silk to stick pieces of pebbles, sticks, or other debris into a portable case around their body. One family of caddisfly is free-living, building neither a case nor a retreat.
