Polyandry and fecundity in the Lepidoptera: can methodological and conceptual approaches bias outcomes?
Polyandry is a reproductive strategy whose occurrence has been explained in terms of both direct and indirect benefits to females. Among the direct benefits, a positive correlation between female remating and fecundity, mediated by receipt of nuptial gifts, is considered a major factor maintaining polyandry.
