Obligate hematophages (blood feeders), primarily feeding on human blood but will feed on other warm-blooded animals if necessary.
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 into each successive stage.
