Summary
Cimicinae is a subfamily of blood-feeding insects known as cimicids or bed bugs, characterized by traumatic insemination and a specialized diet mostly consisting of the blood of warm-blooded hosts such as bats, birds, and humans. They possess adaptations allowing them to survive long periods without feeding and exhibit complex reproductive behaviors.
Physical Characteristics
Small, oval, flattened, wingless insects; body bulges after feeding; beak-like mouthparts for piercing skin and sucking blood.
Identification Tips
Cimicids do not fly and possess small, non-functional wing pads. They can be differentiated by their feeding habits and reproductive practices, particularly traumatic insemination.
Habitat
Typically found in nests, roosts, or dwellings of their vertebrate hosts including bats, birds, and humans.
Distribution
Widespread, with over 100 species found globally; associated with warm-blooded animals.
Diet
Exclusively blood-feeders; primarily consume the blood of bats, birds, and humans.
Life Cycle
Undergo five nymphal instars, each requiring a blood meal to progress to the next stage; complete development can vary based on feeding conditions.
Reproduction
Involves traumatic insemination where males pierce females to fertilize eggs directly; egg-laying behavior varies among species.
Ecosystem Role
Acts as ectoparasites, influencing host population dynamics and potentially playing a role in pathogen dynamics.
Economic Impact
Human cimicids, such as Cimex lectularius, can have significant impacts on human habitation and well-being due to their parasitic nature.
Cultural Significance
Often viewed negatively due to their association with unsanitary living conditions; have been a subject of folklore and urban issues due to infestations.
Health Concerns
Can cause immune responses, secondary infections, and discomfort in hosts; potential vectors for some pathogens, though transmission is rare.
Collecting Methods
- Trapping during host interactions
- Visual searches in known habitats
Preservation Methods
- Alcohol preservation
- Freezing to kill specimens
Evolution
Cimicidae is related to Polyctenidae; evolved to feed on birds and bats; has colonized humans on multiple occasions; evolutionary origins date back to the Cretaceous period.

Misconceptions
Often confused with general pests; not all species feed on humans or transmit diseases effectively.
