Abstract

Species where most but not all females mate monandrously can provide insight into the potential factors both promoting and restricting polyandry. Polyandry is typically explained by direct and/or indirect benefits models; however, polyandry may also confer costs via sexually antagonistic processes. The fitness of polyandrous and monandrous females may also vary with environmental conditions, such as availability of water. For some lepidopterans, water is a vital resource that increases fecundity and may be a direct benefit of multiple mating. Male lepidopterans transfer large spermatophores that may be an important water source for females, particularly for species living in water-depauperat..
