Abstract
Aphids are short-lived and occupy habitats which vary in quality in both time and space. They exploit their ephemerally nutritious habitats by rapidly producing many small offspring when conditions are good, and fewer, larger offspring when conditions are poor, at which time they also divert more of their resources into fat storage. Aphids of each of the generations which make up a life cycle have specific reproductive strategies adapted to the conditions they are most likely to encounter, that is they anticipate the predictable seasonal trends in habitat quality.
