The pteromalid wasp Anisopteromalus calandrae (Howard) is a parasite of larval instars of several species of beetles. In our experiments we used larvae of the granary weevil (Sitophilus granarius L.) as hosts. Host size may differ considerably, older larvae being much larger than younger ones. Fitness of the wasps' offspring depends on host size but differences between small and large sons are probably less than between small and large daughters.
