Butterflies display extreme variation in wing shape associated with tremendous ecological diversity. Disentangling the role of neutral versus adaptive processes in wing shape diversification remains a challenge for evolutionary biologists. Ascertaining how natural selection influences wing shape evolution requires both functional studies linking mo...
Morpho butterflies are iconic insects of the Amazonian rainforest. Some Morpho species live in the dense vegetation of the understory (e.g. Morpho amathonte, present photo) while other species inhabit the open canopy. Le Roy et al. (jeb243867) investigated how the divergent microhabitat specialisation influences the evolution of flight performance....
Habitat specialization can influence the evolution of animal movement in promoting divergent locomotor abilities adapted to contrasted environmental conditions, differences in vegetation clutter or predatory communities. While the effect of habitat on the evolution of locomotion and particularly escape performance has been well-investigated in terr...
The coexistence of closely-related species in sympatry is puzzling because ecological niche proximity imposes strong competition and reproductive interference. A striking example is the widespread wing pattern convergence of several blue-banded Morpho butterfly species with overlapping ranges of distribution. Here we perform a series of field exper...
Strategic fliers
Forests are often crowded and complex, presenting numerous and varied challenges for species flying through them. Le Roy et al . looked at the Amazonian Morpho butterfly group and found differences in both morphological and behavioral perspectives across species that occupy the canopy relative the understory. Species that evolved t...
Flying insects frequently experience wing damage during their life. Such irreversible alterations of wing shape affect flight performance and ultimately fitness. Insects have been shown to compensate for wing damage through various behavioural adjustments, but the importance of damage location over the wings has been scarcely studied. Using natural...
