摘要

Males of the moth Gluphisia septentrionis acquire sodium by drinking from mud puddles. Analyses of male and female bodies indicate that such "puddling" behav- ior enables the male to provide his mate with a nuptial gift of sodium, presumably via the spermatophore. This gift (about 10 μg), amounting to more than half of a puddler male's total body sodium, is in large measure apportioned by the female to her eggs.
