Biased dispersal ofMetrioptera bicolor, a wing dimorphic bush‐cricket
Insect Science, 2017AbstractIn 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.

Short-winged forms of the bug, Jadera aeola, were discovered during the late dry season at a study site on Barro Colorado Island, Panama. They were smaller than long-winged adults not only in elytron and hindwing sizes but also in head, thorax, rostrum and hind femur dimentions. When newly emerged adults were kept under natural photothermal conditions,

Sexual Dimorphism CURE: Exploring Melanized Wing Patterns of Pieridae Butterflies
2022Teach a Course-based Undergraduate Research Experience (CURE) using digitized natural history collections data to test hypotheses on sexually dimorphic wing melanization patterns of Pieris rapae butterflies. This inclusive CURE can be implemented in in-person, online, and hybrid formats, synchronously or asynchronously, and requires only student access

The physiological costs of flight capability in wing‐dimorphic crickets
Population Ecology, 1994AbstractNutritional indices, triglyceride levels and flight muscle developmental profiles were compared between long‐winged (LW) and short‐winged (SW; flightless) morphs of the crickets Gryllus rubens Scudder and G. firmus Scudder. This was done to identify potential physiological costs of flight capability in adults.

The evolutionary significance of wing dimorphism in carabid beetles (Coleoptera: Carabidae)
Population Ecology, 1995Abstract A review of data on the background of wing dimorphism in carabid beetles (Coleoptera: Carabidae) and especially of the closely related Calathus cinctus and C. melanocephalus is given. In both Calathus

Variation in fighting strategies in male wing-dimorphic crickets (Gryllidae)
Behavioral Ecology and Sociobiology, 2016Because a trade-off between reproduction and dispersal has been commonly found in wing-dimorphic insects, males of different wing morphs may have a different demand on a mate or a territory. We hypothesized that males of wing-dimorphic insects may vary in fighting success over these two resources.

Dimorphism of tergal wing-folding spicule patches and wing-toiletry fringes accompanies wing dimorphism in the ladybird, Rhyzobius litura. Such dimorphism of ‘ancillary' structures is of rare occurrence in the Coleoptera; other instances are discussed. Data are presented concerning the incidence of long and short winged individuals of R.

Why is there so much genetic variation for wing dimorphism?
Population Ecology, 1994AbstractWing dimorphism appears in general to be determined either by a single locus, 2 allele system in which brachyptery is dominant, or by the additive action of numerous loci. In the latter case studies indicate that the heritability is typically quite large.
