Illustrations of Tsetse Larvae

Abstract

Some of the structures illustrated here have already been noticed in two previous papers (Jackson, 1948a & b). All the present drawings were made by one of us (E.B.) from living material of Glossina swynnertoni Austen. The eggs and the first- and second-instar larvae were dissected from wild female flies and examined in saline under the microscope; the third-instar larvae were obtained by keeping females in captivity until larviposition occurred, normally in the late afternoon.
