Declan McCabe teaches biology at Saint Michaels College. The larvae build cases made of small rocks, sand grains and bits of vegetation cemented together with silk from their mouths in which they hide during the day to protect themselves against predators such as fish or frogs. All members of the order Trichoptera are aquatic as in the stages of larvae and pupae, while adults are terrestrial.

MeSH Colors are usually dark and drab, although the hindwings, usually hidden beneath the forewings, are often clear. Case-building caddisflies are more commonly found in cleaner streams. Some species have branched gills or humps on the sides of the body (in order to increase the body surface). They protect soft abdomen from predators and abrasion from coarse particles drifting in stream. Some cases are spiral like a snail shell. Larvae are sensitive to pollution and for this reason are used worldwide as the indicators of water quality. Movement: The plants are still in the quarantine tank so I don't have to worry about the big tank having them. The larvae construct silk pouches which they attach to underwater objects to protect themselves during a long developmental period called the pupa .

In areas with faster current caddisflies make cases out of sand and rocks that are heavy and not as easily swept away. Cases come in large variety of shapes and structures. Position and size of the plates are often important identification features among the species. Their life cycle includes four stages egg, larva, pupa and adult. The larvae are sensitive to pollution and thus serve as an indicator of water quality. Underwater Caterpillar? 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.
