"Eukiefferiella" and "Tvetenia" are closely related genera belonging to the subfamily Orthocladiinae within the Chironomidae, a family of non-biting midges. All known larvae in these genera are aquatic, being found predominantly in running water. Most species prefer cold, swift-flowing, well-oxygenated streams. Although larvae…

Describes the role of mushroom bodies--cup-shaped structures perched atop the brain of an insect--in learning. Mushroom bodies may help fruit flies in learning meaningful odors, cockroaches in spatial learning, and honeybees both in locating pollen and nectar and in navigating back to the colony. (PVD)

Substances that deliver chemical messages between same/different species are called semiochemicals. Surveyed are three types of semiochemicals (pheromones, allomones, and kairomones), types of organisms involved, and specific chemicals used to carry the various kinds of messages. (JN)

Discusses reasons for the success of insects, considering their size, reproductive ability, development, and adaptability. Also discusses various types of insect "homes" (such as galls and paper nests). (JN)

This article: (1) explains the respiratory patterns of several freshwater insects; (2) describes the differences and mechanisms of spiracular cutaneous, and gill respiration; and (3) discusses behavioral aspects of selected aquatic insects. (ML)

Explores the relationship between invention/innovation in pest control practices, food supply, and hunger in the United States from 1920-1970. Includes discussions of the nature, development, and use of insecticides, control of specific pests, and public arguments over the safety of residues leading to search for nonchemical methods of control.…

Water striders are insects that walk and run on the surface of water. Discusses the morphology, physiology, and behavior of these insects. Includes diagrams of stages in the movement of a typical strider. (JN)

The British National Curriculum calls for children to work with living things. Discusses alternatives available for teaching children about bugs, most notably through models and live animals kept in school. Models prove valuable for introducing children to bugs and for stimulating them to ask scientific questions. Raises issues behind keeping live…
