Insect life-cycle polymorphism: Introduction,ngly wide spectrum of interspecific variation in larval development. At one extreme is found the highly specialized fly living in termite nests, . Schmitz; the adult lays a (relatively) huge egg which hatches immediately, and the larval stage lasts for only a few minutes before forming a puparium (M

Diversity and integration of life-cycle controls in insects,ive forces are diverse; consequently, adaptations that budget time represent trade-offs among different objectives. Many different patterns of trade-offs in time and energetic resources, for example between duration of development and size, size and fecundity, and fecundity and longevity, appear in

Evolutionarily stable seasonal timing of univoltine and bivoltine insects,on dates are under natural selection. A first case assumes that competition among feeding larvae can be neglected. Under this assumption, bivoltine life cannot be optimal if the growth rate increases in proportion to the body weight. If growth rate increases slower than proportionality, and if the r

Variation of carabid life cycles along climatic gradients: An adaptive perspective for life-historye carabid beetles by integrating information from physiological and population ecology, biogeography, and mathematical theory. Among the two major categories of seasonal life cycles in carabids, autumn breeders with larval overwintering are better adapted to colonize cool habitats than spring breede

Fallibility

Variation in diapause characteristics and its consequences on population phenomena in the two-spott capacity for diapause is also highly variable within populations at intermediate latitudes; individuals have different threshold temperatures for phenotypic expression of diapause and they either reproduce or enter diapause in response to temperature conditions in autumn. Such populations thus incl
