The Cimicidae are a family of small parasitic bugs that feed exclusively on the blood of warm-blooded animals. They are called cimicids or, loosely, bed bugs, though the latter term properly refers to the most well-known member of the family, Cimex lectularius, the common bed bug, and its tropical relation Cimex hemipterus.

A small proportion of the species are serious pests of commercially important crops. Some of these serve as vectors for over 20 viruses that cause plant disease, especially the Tospoviruses. Many flower-dwelling species bring benefits as pollinators, with some predatory thrips feeding on small insects or mites. In the right conditions, such as ...
Adult males in contrast have the typical head, thorax and abdomen of other insect groups, and are so different from females that pairing them as a species is challenging. They are usually slender insects resembling aphids or small flies. They have antennae with nine or ten segments, compound eyes (Margarodidae and Ortheziidae) or simple eyes ...
Humans have interacted with the Hemiptera for millennia. Some species, including many aphids, are significant agricultural pests, damaging crops by sucking the sap. Others harm humans more directly as vectors of serious viral diseases. The bed bug is a persistent parasite of humans, and some kissing bugs can transmit Chagas disease.
Corixidae is a family of aquatic insects in the order Hemiptera.They are found worldwide in virtually any freshwater habitat and a few species live in saline water. [1] There are about 500 known species worldwide, in 55 genera, including the genus Sigara.
Lethocerus americanus, sometimes called the electric light bug, toe biter or fish killer, [1] is a giant water bug in the family Belostomatidae, native to southern Canada and the United States (north of 35°N; other Lethocerus species are found southwards). [2] It typically has a length around 5–6 cm (2.0–2.4 in). [3]
They feed primarily on aquatic invertebrates such as other insects, but occasionally take small fish or tadpoles. The eggs, which are laid above the waterline in mud, decomposing vegetation, the stems of plants or rotting wood, are supplied with air by filamentous processes which vary in number among the genera.

The adult stage of a caddisfly may only survive for a few weeks; many species do not feed as adults and die soon after breeding, but some species are known to feed on nectar. [19] The winged insects are nocturnal and provide food for night-flying birds, bats, small mammals, amphibians and arthropods.
