Examples of maternal effects are: the increased ability of autumnal moth (Epirrita autumnata) caterpillars to feed on foliage with induced defensive chemicals if their mothers originated from a high-density population (Haukioja and Neuvonen 1987); the variation in egg size and associated cold tolerance in spruce budworm, Choristoneura fumiferana (Harvey 1985); the variation of western tent caterpillar (Malacosoma californicum pluviale) activity and survival with the history of the mother in such a way that food-stressed mothers produce less active caterpillars (Wellington 1965); and the variation in survival of offspring with food quality of the parental generation of fall webworm, Hyphantria cunea (Morris 1967).
