Habitat Persistence and the Evolution of Wing Dimorphism in Insects

The American Naturalist, 1994
Wing dimorphism occurs commonly among many species of insects. This dimorphism is hypothesized to be maintained by a trade-off between the costs of being macropterous (winged, flight capable) and the long-term benefits of migration in a heterogeneous environment.

Role of monoamine metabolism in wing dimorphism of the aphid Myzus persicae

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1976
Abstract 1. 1. Wing dimorphism of the aphid Myzus persicae which normally is regulated by a number of exogenic factors can be influenced by neuropharmaca. 2. 2. With micro-injections of drugs that are known to act on monoamine metabolism it is possible to direct the course of development towards the alate or apterous morph. 3.

Wing Dimorphism in Field Crickets (Orthoptera: Gryllidae: Gryllus)

Annals of the Entomological Society of America, 1986
Adult Gryllus are either short-winged (hind wings [HW] shorter than fore wings [FW]: HW/FW 1). Short-winged individuals are flightless, whereas long-winged individuals generally can fly. Hind wings are not shed after flight. Of five species occurring in peninsular Florida, G. ovisopis Walker is always short-winged (mean value of HW/FW ratio = 0.5), G.

Modeling the Evolution of Phenotypic Plasticity in Resource Allocation in Wing‐Dimorphic Insects

The American Naturalist, 2010
In nature, resource availability varies spatially and temporally both within and across generations, leading to variation in the amount of energy available to individuals. The optimal allocation strategy can change, depending on the amount of resources available to allocate to life-history functions.

Biased dispersal ofMetrioptera bicolor, a wing dimorphic bush‐cricket

Insect Science, 2017
AbstractIn the highly fragmented landscape of central Europe, dispersal is of particular importance as it determines the long‐term survival of animal populations. Dispersal not only secures the recolonization of patches where populations went extinct, it may also rescue small populations and thus prevent local extinction events.

Wing Dimorphism and Diapause in Gerris: Determination and Adaptive Significance

1978
Water-striders of the genus Gerris Fabr. consist of a small group of predatory bugs living on the water surface. In temperate climates the habitats often freeze in the winter, and gerrids overwinter on dry land as imagos. The morphology of the species restricts them to habitats protected from wave action.
