The body size of the host insect in which a parasitoid develops can have important effects on its development and life history. Large and small host body size have both been suggested to be advantageous to parasitoids, depending on the life-history of the species concerned. We test field data on the bumblebeeBombus terrestris and its conopid parasitoids for evidence of differences in size between parasitised and unparasitised worker bees. Bees acting as hosts for conopid parasitoids are on average larger-bodied than unparasitised bees. This result holds for bees collected in two different years, and whether bees are collected while foraging or from the nest. The results we present demonstrate differential parasitism of hosts of different body sizes, but do not necessarily indicate active host choice by conopids. However, they are in agreement with independent evidence that conopids develop more successfully in large-than in small-bodied hosts.
