This designation is called a Tolerance score and ranges from 0-10 with zero being the least tolerant to pollution. Aquatic insects are a large and diverse group of organisms that live in different aquatic environments. The nymphs and adults often look nothing alike, but each can be identified by unique morphological features, such as tails, gills, and overall shape (see table on page 2). Following the easy-to-read BUGKIT manual, one to two students learn to collect, observe, sort, and identify aquatic insects as a tool for measuring water quality. The most notable group of secondary invaders is the insects, many of which still have terrestrial adults. Water insects or aquatic beetles are biological indicator. The insect integument, especially the wax layer of the epicuticle, appears to be especially important in pre-venting flooding of the tissues (Chapman 1982). Knowing how α-, β- and γdiversity of aquatic insects vary along geographical and environmental gradients has important implications for the conservation of biodiversity in freshwater ecosystems. Most successful freshwater invasive taxa complete their life cycle in the water and lack a terrestrial or aerial stage . Water insects or aquatic beetles are biological indicator.

The fossil record suggests that all aquatic insect groups are the result of the invasion of fresh-waters by terrestrial groups (143). As part of their life cycle, aquatic insects transition from aquatic larvae to terrestrial adults, thereby linking freshwater ecosystem processes and terrestrial insectivore dynamics. Macroinvertebrates are animals without a backbone that can be seen with the naked eye. About 5,000 species of insects are estimated to inhabit inland wetlands of India.

Piercers using their long and curved (stylet-like) mouthparts to pierce the cells or freshwater sponges and suck the fluids. They grow quickly and can survive in a variety of habitats, but they are most prolific and important to trout in slow, weedy spring creeks. Then, when they undergo their final molt, they leave the water and become winged adults that fly in the air. 6. These insects like the slow moving clear waters of freshwater streams and ponds. Aquatic insects that live in the lake as larvae (caterpillars) often spend a year or more in the water eating and growing before they are ready to fly away as adults. These are carnivorous insects that seize their prey with their front limbs and suck out its body fluids.
