Further progress in understanding insect cold-hardiness requires a broader perspective than hitherto. Such a broader approach is feasible, given the range of information now available on cold-hardiness and the variety and quality of equipment to study it. Comprehensive information on individual species is required, using the full range of available techniques, instead of piecemeal investigations. Comparisons of species must likewise be based on how their complete cold-hardiness strategies are structured, rather than on any particular contrasts between individual elements. Most importantly, a well based understanding of cold-hardiness requires wider linkages between cold-hardiness and other salient aspects of the life cycle, such as seasonal timing and control, water balance, and metabolism and energy budgets. Cold-hardiness is only one aspect of the adaptive trade-offs that structure the life cycle of any given species.
