Diet & Feeding

Obligate hematophages; feeds exclusively on the blood of warm-blooded animals, primarily humans.

Behavior Patterns

Nocturnal creatures that emerge at night to feed on sleeping hosts. They are attracted by body heat and carbon dioxide, undergoing complete metamorphosis through five nymphal stages before reaching adulthood.

Risks & Benefits
