Schematic of the experimental design. Winter moth livestock from four British populations were reared to pupation on foliage from nine different host-plant species. Caterpillars were reared in cultures of 20 individuals, assigned to each culture randomly across broods. Performance in each host-by-population treatment was quantified on three metrics: survival, pupal mass attained, and development time (time from egg hatch to pupation)
