Size Effects on Mating and Egg Production in the Miami Blue Butterfly

Article

Abstract

Body size is often related to reproductive success in insects, but the direction and strength of this relationship differs greatly among systems. We studied the effects of adult size on probability of mating and egg production in the Miami blue butterfly. We found that likelihood of mating was invariant with respect to size. Larger females lived longer, and both size and lifespan positively influenced egg production. However, neither the number of copulations nor the size of male mates had any effect on female fecundity. We discuss these results in the context of butterfly mating systems, larval growth strategies and the possible effects of captive conditions on reproductive behavior.
