The eggs of three species of Mallophaga and their significance in ecological studies

The eggs of Ricinus picturatus, Menacanthus sp., and Philopterus sp. (Mallophaga) taken from the orange-crowned warbler (Vermivora celata) are described. The location of the eggs on the feathers and in various feather tracts is reported. It is suggested that museum study skins will provide a valuable source of data concerning distribution and ecology of egg-laying in Mallophaga if the presence of louse eggs, rather than adults or nymphs, is studied.
