Two poplar hawk-moths in the process of mating, the pairing of opposite-sex or hermaphroditic organisms, generally for the purposes of sexual reproduction. Mating may involve copulation if the species' fertilization is internal, but not if it is external. Different species use different strategies to select a mate, including random mating, disassortative mating, assortative mating, and a mating pool.Photograph: Kateshortforbob
