During courtship and mating, insect males often transfer
materials to females beyond the requisite gametes. Such nuptial
gifts represent a fascinating convergence of sexual selection,
nutritional ecology, and life history evolution. Especially among
insects that feed only during their juvenile stage, nuptial gifts
can strongly impact adult reproductive output for both sexes.
However, little is known concerning factors that drive the evolution
of nuptial gifts.
