Abstract

The observations recorded here were made during the course of a series of studies on the activities of Formica rufa melanotica Emery. In this species all the workers are deeply infuscated with black: the smallest workers are entirely black; the largest workers are very dark with clear red head; between these two is a series of intermediate forms with dark head. It has already been established that most of the workers engaged in moving a colony to a new nest were red-headed major workers (Sallee and King, 1947), and observations indicated that most of the workers attending aphids were black-headed minors. This brought up the question of the degree of differentiation and relative numbers of workers in a colony of this species.
