"Picking out a "jigger"". Exterior view of a girl seated with her legs across another girls lap. The second girl is using a pin to remove a jigger, sand-flea, from the toe of the first girl. The sand-flea, or Sarcopsylla penetrans, arrived in Africa in 1872 on the British ship Thomas Mitchell, in a cargo of ballast from Rio de Janeiro; by 1898 it had spread the width of the continent. They cause intense pain and irritation as the females burrow into the skin of mammals to lay eggs, in humans this is usually exposed areas such as the feet and hands.
