Wet Season Fraying of Wings of Tsetse-flies, Glossina morsitans

Abstract

The wings of male Glossina morsitans appear to become frayed in the rainy season at about the same rate as in the dry season, and their brittleness seems directly related to age. The law of diminishing returns does not appear to apply, perhaps because of the weakening of portions of the trailing edge between indentations fairly near together.
