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.

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 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.

Integrated phylogenomics and mitochondrial DNA inventory of net-winged beetles across three continents suggest ~1000 undescribed species, biodiversity hot spots, and phylogeny-based classification that sets up the basis for further research.

Body color change of locusts reveals a new 'palette effect' mechanism by which the red βCBP–β-carotene pigment complex acts as a switch to coordinate between black and green coloration.

The BTB zinc finger gene Bm-mamo regulates melanin pigmentation in silkworm caterpillars from multiple aspects, including melanin synthesis, pigment granules maturation, and cuticle construction.

Two neuropeptides, NPF1a and NPF2, act via the nitric oxide signaling pathway in the locust brain to regulate the trait transition between solitary and swarming behavior.
