Rhagoletis basiola
rosehip fly
Rhagoletis basiola is a tephritid fruit fly native to North America, commonly known as the rosehip fly. Females oviposit in rosehip fruits and deposit host-marking pheromones post-oviposition, a behavior that deters conspecific competitors but attracts parasitoids. Egg production imposes measurable survival costs on adult females, representing a documented life history trade-off.
