A species of flea (Tunga penetrans
, formerly Pulex penetrans
), common in the West Indies and South America, which often attacks the feet or any exposed part of the human body, and burrowing beneath the skin produces great irritation. When the female is allowed to remain and breed, troublesome sores result, which are sometimes dangerous. See Jigger
. [1913 Webster
" The name is sometimes erroneously given to certain mites or ticks having similar habits."
