Life cycle of the Chigoe Flea (Tunga penetrans)Eggs are shed by the gravid female into the environment (1). Eggs hatch into larvae (2) in about 3-4 days and feed on organic debris in the environment. Tunga penetrans has two larval stages before forming pupae (3). The pupae are in cocoons that are often covered with debris from the environment (sand, pebbles, etc). The larval and pupal stages take about 3-4 weeks to complete. Afterwards, adults hatch from pupae (4) and seek out a warm-blooded host for blood meals. Both males and females feed intermittently on their host, but only mated females burrow into the skin (epidermis) of the host, where they cause a nodular swelling (5). Females do not have any specialized burrowing organs, and simply claw into the epidermis after attaching with their mouthparts. After penetrating the stratum corneum, they burrow into the stratum granulosum, with only their posterior ends exposed to the environment (6). The female fleas continue to feed and their abdomens extend up to about 1 cm. Females shed about 100 eggs over a two-week period, after which they die and are sloughed by the host’s skin. Secondary bacterial infections are not uncommon with tungiasis.From Centers for Disease Control Parasites and Health website
