Natural Habitat

Diet & Feeding

Obligate hematophages (blood-feeders), primarily feeding on human blood during the night.

Behavior Patterns

Nocturnal parasites that hide during the day and emerge at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult) and require a blood meal to molt.
