Biology of the Oestroidea — The Phenomenon of Aggregation

Abstract

Both Cuticolae and Cavicolae depend, during the larval stage, entirely upon their hosts, and are dispersed by the mammals as they move around. Consequently, when dropping to the ground to pupate, the mature larvae of one population will be scattered over a more or less large area. Upon emergence, adults will appear in different areas, in most cases very distant from each other.
