ABSTRACT
A perusal of the literature on the ecology and behavior of aquatic insects reveals the dearth of detailed information on most species. Biological control of the larvae of blood-sucking insects and pests that feed on aquatic crops, such as rice, taro, sweet potato, yam, or lotus, is another field of investigation that has been neglected until very recently. In addition, discoveries in the fields of insect ecology, physiology, biochemistry, behavior, zoogeography, and related fields are likely in places that have rarely been visited before. Lotic habitats, on the other hand, are more likely to show declines in the numbers of aquatic animals and in species diversity. The adults are very small and inconspicuous. They lay their eggs on or inside one of several species of freshwater sponge in the genus Spongilla. For some reason, entomologists have failed to report seemingly intelligent behavior by insects, with the exception of certain practices of social species of Hymenoptera.
