Tunga penetrans (Chigoe flea)

Natural Habitat

Found in tropical and subtropical regions of the world, including parts of South America, the Caribbean, and sub-Saharan Africa. They typically live in dry, sandy soil or dust in and around homes and livestock areas.

Diet & Feeding

Adults feed on the blood of mammals, including humans, pigs, dogs, and cats.

Behavior Patterns

Unlike most flea species, the female Tunga penetrans burrows into the skin of its host (usually under the toenails or between the toes). Once embedded, it stays there to feed and develop eggs, which are then shed into the environment. After several weeks, the flea dies and remains embedded in the skin.

Risks & Benefits

Risks: Causes tungiasis, an inflammatory skin disease characterized by extreme pain, itching, and potential secondary bacterial infections (like tetanus or gangrene). There are no known benefits to the ecosystem or humans.
