Summary
Cimicidae, or bed bugs, are a family of small ectoparasitic insects that exclusively feed on the blood of warm-blooded hosts, including humans, bats, and birds. They are known for their unique reproductive method of traumatic insemination, multiple life stages, and ability to survive extended periods without feeding.
Physical Characteristics
Small, oval-shaped, and flat appearance; bodies bulge after feeding; non-functional wing pads; beak-like mouthparts for feeding.
Identification Tips
Cimicids are characterized by their flat bodies, lack of wings, and the presence of segmented legs with claws (in some species).
Habitat
Cimicids are typically found in nests or roosts of their hosts, including birds, bats, and humans. They prefer environments where hosts return regularly to roost or nest.
Distribution
Cosmopolitan; present in various regions worldwide, with specific preferences for areas where bats and birds congregate alongside human dwellings.
Diet
Exclusively hemato-phagous; primarily feed on the blood of warm-blooded animals, notably bats, birds, and humans.
Life Cycle
Multiple generations per year; development includes five nymphal instars that require a blood meal for each stage of growth.
Reproduction
Involves traumatic insemination, where males pierce females' abdominal walls to inject sperm; females lay eggs after feeding, dependent on successful insemination.
Predators
Predation risk is mitigated by hiding in concealed locations; specific predators are not well-documented but may include various insectivorous animals.
Ecosystem Role
Ectoparasites that may influence the health of their hosts and the dynamics of host-parasite relationships; they also serve as potential vectors for certain pathogens.
Economic Impact
Notable pest species (e.g. Cimex lectularius) can cause discomfort and distress to humans; associated with cost of pest management in human dwellings.
Cultural Significance
Cimex lectularius, known as the common bed bug, has significant historical and contemporary relevance due to its effects on human populations and domestic settings.
Health Concerns
May potentially harbor pathogens but do not generally transmit diseases to humans; risk of secondary infections at feeding sites exists.
Collecting Methods
- Sticky traps
- Manual collection
Preservation Methods
- Ethanol
- Freezing
Evolution
Cimicidae likely evolved from predatory ancestors; significant diversification occurred in the Cretaceous period; hosts switched to bats after their evolution.

Misconceptions
Cimicids are often confused solely as pests without awareness of their complex life cycle and evolutionary history with birds and mammals including humans.
