Explanation of Names
Cimex lectularius Linnaeus 1758
lectul (L). 'a couch, bed' (1)
7 spp. of Cimex in N. Amer. (2)
6 mm or less, according to Peterson's A Field Guide to the Insects and Roger Bland's How to Know the Insects
5 to 9.5 mm, U. of Florida
body reddish-brown, ovoid, broadly flattened, with greatly reduced wings; forewings (hemelytra) broader than long, somewhat rectangular; sides of pronotum covered with short stiff hairs (fringe hairs on pronotum shorter than width of eye)
"Truly cosmopolitan" (2)
on or near host animal (humans)
parasitic: nymphs and adults feed on blood of host animal
Life Cycle
multiple generations per year
"Mating occurs off the host and involves a unique form of copulation called ‘traumatic insemination’ whereby the male penetrates the female’s abdominal wall with his external genitalia and inseminates into her body cavity. Adults live 6-12 months and may survive for long periods of time without feeding." - CDC
Introduced from Europe by early colonists.
Suspected, but never proven, of transmitting 41 human disease organisms (2)
"While Cimex spp. have been found to be naturally-infected with several blood-borne pathogens, they are not effective vectors of disease. The primary medical importance is inflammation associated with their bites." - CDC
