The tropical butterfly, Bicyclus anynana, exhibits seasonal polyphenism. The wet season
form has large eyespots and a pale band while these characters are much less conspicuous …

Adults of the butterfly Bicyclus anynana express striking phenotypic plasticity. A wet season
form has conspicuous marginal eyespots and a medial pale band which are much reduced …

The genetic basis of the dry‐wet season polyphenism of wing pattern in response to
temperature shown by Bicyclus anynana was studied, using a split‐family design over four …

Temperature‐induced variation and norms of reaction have been analyzed for wing pattern
elements of six species belonging to the African butterfly genus Bicyclus (Lepidoptera …

Phenotypic plasticity may enable organisms to maximize their fitness in seasonally variable
environments. However, in butterflies, seasonal polyphenism is often striking but functionally …

The tropical butterfly Bicyclus anynana shows adaptive phenotypic plasticity in response to
wet–dry seasonality. The wet season form (WSF) has a conspicuous wing pattern with large …

The temperate‐zone butterfly Pararge aegeria can use three developmental pathways
corresponding to different seasonal cohorts:(1) development with a pupal winter diapause …

The tropical butterfly Bicyclus anynana shows phenotypic plasticity in its ventral wing pattern
as an adaptive response to wet‐dry seasonality. Wet season form individuals have large …

Genetic correlations (rg) within and across environments, were determined in the tropical,
dry-wet seasonal polyphenic butterfly Bicyclus anynana, over four temperatures, for larval …

An explanation is developed for the adaptive significance of the forms characteristic of the
dry season and wet season adult generations of some tropical butterflies. The divergent …
