Filter feeding in aquatic insects. This is the happiest moment for the authors to present Ecology of Aquatic Insects to readers of this discipline. Study of any organism without considering its ecology is not complete as no organism can be separated from its environment. About 75% of earth's surface is covered by water which is source of life on earth. It is the medium within which all aspects of ecosystem co exist both living and non living. Insects have adopted themselves to occupy almost every conceivable ecological niche in on or above the earth. They are all around us occupying our houses puncturing our skin consuming our food and clothing. There is scarcely any place on the earth that is not home to atleast one kind of insects. They endure all extremes of environment and are the most successful group of animals from Protozoa to mammals. This is an attempt to provide distinct advantage to its user (undergraduate postgraduate and life science students and also the researchers who are engaged in deciphering the mystery of aquatic ecology) towards better understanding of relation between insects and aquatic environment. 240 pp.
