Carnus hemapterus is a Dipteran insect, a small-bodied and partly black-coloured carnid fly. In their adult stage of life, they are blood-sucking ectoparasites of nestling birds. Within the genus Carnus, this is the only species widespread across Europe and the cold and temperate regions of Asia and North America. Female body length is about 1.5 mm, males are smaller. It typically occurs in the nests of medium- to large-bodied birds, provided that the nest is not on the ground. It is particularly common on the chicks of owls, falcons, rollers, bee-eaters and starlings. Females give birth to larvae that live within the nest and feed on organic debris and the pupae also overwinter there. The emergence of imagines is synchronized to the hatch of host nestlings in the subsequent year. They prefer larger chicks within the nest. Adult flies have a winged and an unwinged variety, the latter being much commoner. In fact, unwinged flies still carry the basal part of their wings, but the majority of the wing is broken off. Flies live only on the nestlings before and during the development of the plumage, and disappear later on.

The tarnished plant bug (TPB), Lygus lineolaris, is a species of plant-feeding insect in the family Miridae. It has piercing-sucking mouthparts and has become a serious pest on small fruits and vegetables in North America. It is considered a highly polyphagous species and feeds on over half of all commercially grown crop plants, but favors cotton, alfalfa, beans, stone fruits, and conifer seedlings. A study done in southwestern Quebec, Canada has investigated the presence of L. lineolaris in a commercial vineyard. This study also indicated that weeds that grow from cultivation of crops serve as an important food source for L. lineolaris. This insect can be found across North America, from northern Canada to southern Mexico. Adults grow up to 6.5 mm in length, and are brown with accents of yellow, orange or red, with a light-colored "V" on the back (dorsal).
