Book excerpt: Excerpt from Annals of Tropical Medicine and Parasitology, Vol. 5: April 20, 1911, to February 26, 1912 The characteristic attitude of Phlebotomus is portrayed on Plates VI and VII. When at rest the wings slightly diverge and are elevated at a considerable angle above the thorax and abdomen. On the least disturbance the insects make short rapid flights, almost invariably to the right or left, reminding one of the rapid movements of a flea rather than those of a winged insect. Occasionally, however, they will take long - continued flights, when the course is more or less direct and distinctly midge-like. Their movements on the w1ng can be followed with little difficulty in daylight, but by artificial light it'is almost impossible to do so for more than a few seconds at a time. Both sexes live but a short time in captivity, unless they are fed upon human blood. Without this they will subsist on wet blotting - paper or other damp materials, such as soil, fresh leaves, etc. Under such conditions many examples survived for periods varying from three to nine days though the majority died on the third and fourth days, even although the females, in many instances, had taken a meal of blood a few hours before they were captured.
