Entomologia Experimentalis Et Applicata, 2023 AbstractCryptic colouration is an adaptative mechanism against predators. Colour patterns can become cryptic through background matching and disruptive colouration, which breaks up the outlines of an animal because the pattern does not coincide with the shape and outline of the animal's body.

Disruptive colouration in reef fish: does matching the background reduce predation risk? [PDF]
Journal of Experimental Biology, 2017 ABSTRACT Animals use disruptive colouration to prevent detection or recognition by potential predators or prey. Highly contrasting elements within colour patterns, including vertical or horizontal bars, are thought to be effective at distracting attention away from body form and reducing detection likelihood.

Interactions between background matching and disruptive colouration: Experiments using human predators and virtual crabs [PDF]
Environmental Epigenetics, 2015 Abstract Interactions between disruptive colouration and the match between prey and background spot size were manipulated in two experiments that used time taken by human ‘predators’ to find artificial prey (virtual crab morphs) against heterogeneous backgrounds as a measure of the their camouflage.

AbstractDisruptive patterning is patterning which makes an entity difficult to detect and/or identify, but which is independent of the specific local environment, and thus distinct from the background matching mechanism discussed in the previous chapter.

Abstract The Mesozoic froghopper family Sinoalidae was reported from the uppermost Middle–lowermost Upper Jurassic Daohugou Biota and coeval strata of northeastern China, and mid-Cretaceous Kachin amber of northern Myanmar. Herein, a remarkably new sinoalid froghopper, Ornatiala amoena Chen, Wang and Zhang, gen. et sp.

Irradiated Queensland fruit flies (Bactrocera tryoni) used in Sterile Insect Technique (SIT) programmes are marked with fluorescent dyes to distinguish them from wild flies when recaptured in monitoring traps. However, coating sterile pupae with powdered dyes can reduce emergence rates and fly quality and can sometimes produce insufficiently certain ...

Two general models for the transspecific evolution of butterfly colour patterns are advanced: directional selection acting equally on both sexes, and disruptive selection involving periods of polymorphism. To consider possible outcomes of me latter process, a morphism notation based on an integrated classification for polymorphism and sexual dimorphism

Abstract Cryptic colouration is a primary anti‐predation strategy in herbivorous insects. Achieving crypsis often requires acquiring dietary carotenoids—tetraterpene pigments vital for plant colouration and photoprotection.

In Brassica napus, yellow petals had a much higher content of carotenoids than white petals present in a small number of lines, with violaxanthin identified as the major carotenoid compound in yellow petals of rapeseed lines. Using positional cloning we identified a carotenoid cleavage dioxygenase 4 gene, BnaC3.CCD4, responsible for the formation of ...
