Abstract: | Females of the common green blow fly, Lucilia sericata, ovipositing on rat carrion. When females oviposit in aggregations, even‐aged larval offspring develop faster and fewer are preyed upon. These benefits imply that females engage in coordinated, pheromone‐mediated oviposition behavior. Yet, new data show that oviposition site‐seeking females do not respond to pheromones but to semiochemicals associated with gravid or non‐gravid feeding flies, taking chances that resources are suitable for oviposition and that ovipositing flies are present (see pages 651–660).
