In some animals, such as bushcrickets, males donate a nutritious gift to a potential mate, and females ingest this so-called nuptial gift during copulation.
Previously it was thought that most nuptial gift nutrients are routed to egg production.
But, recent studies with isotopically labeled nuptial gifts reveal that female bushcrickets combust nuptial gift nutrients immediately after mating.
Possibly, a male's offspring may benefit indirectly from nuptial gifts, if females have to search less for food and are less likely to fall prey to predators.
