Abstract

The social environment experienced by an individual may have striking effects on its trait expression. We show that an increasing number of conspecifics increased male body mass and the probability of success in aggressive interactions, but decreased courtship activity and tended to decrease sperm number in B. anynana butterflies. Thus, males kept at high densities favored maintenance whereas males kept at low-density favored reproduction, indicating prudent strategic investment.
