In the tropics Dermatohia noxialis lives as a larva in the human skin. Sab Order IV. PUPIPAKA. Very active, often wingless forms living as parasites on mammals and insects; larval development inside tlie mother; pupation occurring soon after birth. 3felopjhagus ovlmis* sheep tick ; Braula caca* bee louse. Order X. Aphaniptera (Siphonaptera). In spite of the lack of wings the fleas are closely related to the Diptera, since they liave doubtless descended from winged forms, as is shown by the fact that tliey liav liolometabolous development. The larva?, long and footless, live in decaying wood or dust in cracks in the.
