LENGTH RANGE Fig. 52. Sexual dimorphism and developmental condition of the sexes in swarms oi E. superba, showing dominance of the male giving way to dominance of the female after pairing has been accomplished (See legend to Fig. 50). samples of the younger and older swarms. In general it will be seen that, up to a point, the dominance of the male, detectable even in swarms consisting of Sixth Furcilias and very early adolescents (Fig. 50, Stations WS 295, 463, 459, 454 and 492), tends to become more pronounced as development proceeds. It does not, however, persist throughout the life of the swarm, tending to disappear when pairing (Fig. 52, Stations WS 152 and WS 373) has been successfully accomplished and the majority of the females, being impregnated, have reached stage 6. From then until it becomes gravid the female rather than the male would appear to be the dominant partner. 28
