Wing transparency in mimetic butterflies and moths is achieved by an unexpected diversity of structural features, and both structures and light transmission properties of wings are under selection for convergence.

A mimetic complex composed of at least 140 species of ants, wasps, spiders, true bugs and treehoppers, all with conspicuous golden bodies, has been discovered.

The detection of low quantities of alkaloids in putatively nontoxic species of poison frogs sheds light on early evolutionary stages of chemical defense in animals.

Some forms of positive density-dependence can favor species coexistence even if competitive species benefit the most from positive density-dependence.

A complex colour polymorphism which links colour with behavioural and life-history traits is associated with a single gene duplication in male wood tiger moths.

The efficacy of eyespots in deterring avian predators is more due to their conspicuousness rather than their resemblance to eyes.

The first genomic view of beetle luciferase evolution indicates evolutionary independence of luciferase between fireflies and click-beetles, and provide valuable datasets which will accelerate the discovery of new biotechnological tools.

Extensive field studies in poison frogs reveal that sex and species differences in parental behavior drive differences in space use patterns but not navigational performance and highlight the interplay between androgen levels and poison frog spatial behavior.
