Descrição: dc.description1. The intensity of community interactions and the structure of food webs can be associated with an organism's body size. However, little is known about how interactions among species in multitrophic communities determine the body size of individuals exploiting the same resource. 2. This study evaluates the effects of resource size, fruit infestation, and parasitism on tibia length, a proxy measure of body size, of insects exploiting the same resource. The three most abundant seed‐feeding species of Senegalia tenuifolia (Fabaceae: Mimosoideae) were selected, and the relationship between their tibia length and the interactions within the food web was estimated. The selected species were the beetles Merobruchus terani and Stator maculatopygus, and the braconid wasp Allorhogas vulgaris. 3. The body sizes of 531 specimens were measured and it was found that tibia length of each species responded differently to the interactions, demonstrating that functionally similar species may respond differently to multitrophic effects. The body size of Merobruchus terani, the most abundant species in the food web, was negatively affected by the presence of A. vulgaris, but there was a positive relationship with seed biomass and its own abundance in the fruits. The other two species were less abundant and more plastic in their responses, as a strong negative effect of M. terani presence on A. vulgaris body size was observed, as well as a strong negative effect of Coleoptera parasitism rate on S. maculatopygus body size. 4. It is concluded that morphological traits can provide information on how interactions affect species body size.-
