This 2006 photograph depicted an oblique-dorsal view of a bed bug nymph (Cimex lectularius) as it was in the process of ingesting a blood meal from the arm of a “voluntary” human host.

There are many bugs that look like bed bugs, so an accurate identification is a critical first step to avoid costly treatment for the wrong bug. The bed bug, Cimex lectularius L. (Hemiptera: Cimicidae), occurs in aggregations (Usinger 1966), consisting of bed bugs in all life stages, feeding statuses, and mating conditions (Johnson 1942, Reinhardt and Siva-Jothy 2007).Bed bugs may aggregate for multiple reasons. 8.10) is a dorso ventrally flattened and oval insect, usually 4–5 mm long.It is reddish brown and gets darker after a blood meal.

Their size ranges between 1 and 7 mm. Distribution (Back to Top) Human dwellings, bird nests, and bat caves are the most suitable habitats for bed bugs because they offer warmth, areas to hide, and hosts on which to feed (Dolling 1991). Cimex species that suck blood from humans (bed bugs) include the tropical and subtropical Cimex hemipterus and its cosmopolitan cousin Cimex lectularius.Both are capable of sucking blood from several animal species.
