Tunga penetrans (Chigoe flea / Jigger flea)

Found in tropical and subtropical regions, particularly in sandy soil, stock enclosures, and dusty floors within rural communities.

The adult female is a parasite that burrows into the skin (typically the feet) of humans and other mammals to feed on blood and tissue fluids for egg production.

The flea jumps onto a host and the female burrows head-first into the epidermis. Once embedded, she remains permanent, breathing through a small opening in the skin while her abdomen swells with eggs.

Causes tungiasis, resulting in severe inflammation, pain, and itching. Left untreated, it can lead to secondary infections like tetanus, gangrene, or loss of nails/toes. It provides no known benefits.
