Background Flight performance and dispersal behaviour can differ between sexes, resulting
in sex-biased dispersal. The primary sex ratio of populations may also explain dispersal bias …

The extrapolation of metapopulation concepts to saproxylic insects suggests that the
occupancy of forest patches and the colonization of ephemeral deadwood substrates are …

Simple Summary We studied the flight dispersal of two congeneric beetle species
(Ochthebius quadricollis and Ochthebius lejolisii) living in Mediterranean coastal rockpools; …

Dispersal dimorphisms, in which both flight‐capable and flightless adults occur in the same
species, are commonplace in insects. Such dimorphisms are seen as reflecting a balance …

Intrinsic factors influencing the dispersal of insect pests during outbreaks are poorly
understood, yet these factors need to be quantified to parameterize dispersal in models that …

Background In most arthropods, adult females are larger than males, and male competition
is a race to quickly locate and mate with scattered females (scramble competition polygyny) …

In dense populations, most planthoppers (Homoptera: Delphacidae) produce fully winged
migratory forms that can escape to new habitats. Under less crowded conditions, flightless …

The widespread occurrence of dispersal polymorphisms among insects is consistent with
the hypothesis that fitness costs are associated with flight capability. Although trade‐offs …

Adaptive plasticity in flight morphology can be of great importance for organisms, in order to
deal with changing environments. When different demands are imposed to this morphology …

Flight polyphenisms naturally occur as discrete or continuous traits in insects. Discrete flight
polyphenisms include winged and wingless morphs, whereas continuous flight …
