The chigoe flea or jigger (Tunga penetrans) is a parasitic arthropod found in tropical climates, especially South and Central America and the West Indies, not to be confused with the larval form of Trombiculidae (called chiggers) found in more temperate climates. In Brazil, the parasite is referred to as bicho de pé. At 1 mm long, the chigoe flea is the smallest known flea. Breeding female chigoes burrow into exposed skin on the feet of mammals and remain there for two weeks while developing eggs, sometimes causing intense irritation. After this point, the skin lesion looks like a 5 to 10 mm blister with a central black dot, which are the flea's exposed hind legs, respiratory spiracles and reproductive organs.
