Drosophila glue protects from predation

Virginie Courtier-Orgogozo, Flora Borne, Stéphane Prigent & Mathieu Molet
Animals can be permanently attached to a substrate in aerial environments at certain stages of their development. Pupa adhesion has evolved multiple times in insects and is thought to maintain the animal in a place where it is not detectable by predators. Here, we investigate whether pupa adhesion in Drosophila can also protect the animal by preventing potential predators from detaching the pupa. We measured the adhesion of Drosophila species sampled from the same area...

PCA coordinates describing dorsal colour pattern variation in 723 Morpho butterflies

Violaine Llaurens, Yann Le Poul, Agathe Puissant, Patrick Blandin & Vincent Debat
Species interactions such as mimicry can promote trait convergence but disentangling this effect from those of shared ecology, evolutionary history and niche conservatism is often challenging. Here by focusing on wing color pattern variation within and between three butterfly species living in sympatry in a large proportion of their range, we tested the effect of species interactions on trait diversification. These butterflies display a conspicuous iridescent blue coloration on the dorsal side of their wings...

Data from: How do predators generalize warning signals in simple and complex prey communities? Insights from a videogame

Monica Arias, John W. Davey, Simon Martin, Chris Jiggins, Nicola Nadeau, Mathieu Joron & Violaine Llaurens
The persistence of distinct warning signals within and between sympatric mimetic communities is a puzzling evolutionary question because selection favours convergence of colour patterns among toxic species. Such convergence is partly shaped by predators’ reaction to similar but not identical stimulus, i.e. generalization behaviour. And generalisation by predators is likely to be shaped by the diversity of local prey. However, studying generalization behaviour is generally limited to simple variations of prey colour patterns. Here, we...
