Adult. Cimex lectularius, or the common bed bug, is a species of Cimicidae.Its primary hosts are humans, and it is one of the world's major "nuisance pests." Although bed bugs can be infected with at least 28 human pathogens, no studies have found that the insects are capable of transmitting any of these to humans. [1]
Bed bug bites are caused primarily by two species of insects: Cimex lectularius (the common bed bug) and Cimex hemipterus, found primarily in the tropics. [3] Their size ranges between 1 and 7 mm. [7] They spread by crawling between nearby locations or by being carried within personal items. [2]
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.

The common bed bug C. lectularius is a wingless, red-brown, blood-sucking insect that grows up to 7 mm in length and has a lifespan from 4 months up to 1 year. Bed bugs hide in cracks and crevices in beds, wooden furniture, floors, and walls during the daytime and emerge at night to feed on their preferred host, humans.
The evolutionary origins of traumatic insemination are disputed. Although it evolved independently in many invertebrate species, traumatic insemination is most highly adapted and thoroughly studied in bed bugs, particularly Cimex lectularius. [1] [3] Traumatic insemination is not limited to male-female couplings, or even couplings of the same ...
Cimex, a genus of small nocturnal insect of which members cause bed bug infestations Cimex lectularius , the most common species of bed bug in temperate regions Cimex hemipterus , a tropical species
Cimex hemipterus, known as the tropical bed bug, is a species of bed bugs within the family Cimicidae that primarily resides in tropical climates. However, it has been reported that this species can live in more temperate climates along with the closely related bed bug species C. lectularius. [ 1 ]
Location of the two mycetomes in the body of an adult Cimex lectularius. A mycetome is a specialized organ in a variety of animal species which houses that animal's symbionts, isolating them from the animal's natural cellular defense mechanisms and allowing sustained controlled symbiotic growth.
