✦ Synopsis

Pre-dispersal seed predators must choose proper hosts and flowers on those hosts that have a high probability of setting seed. In this study, I documented that flowers of Ipomopsis aggregata (Polemoniaceae) chosen by a pre-dispersal seed predator (Anthomyiidae: Hylemya sp.) had a higher probability of seed set than flowers the fly did not choose. I experimentally tested the hypothesis that Hylemya uses a post-fertilization cue in making oviposition choices. I found no evidence for this hypothesis.

Although the importance of pollinators has most often been examined in the evolution of floral characters, seed predators may also play a role in shaping floral evolution. In this study, I examined the role of interplant distance, plant size, and flower morphology on Ipomopsis aggregatás (Polemoniac
