The definition of colour polymorphism is intuitive: genetic variants express discretely-coloured phenotypes. This classification is however elusive as humans form subjective categories or ignore differences that cannot be seen by human eyes. We demonstrate an example of a ‘cryptic morph’ in a polymorphic wood tiger moth (Arctia plantaginis), a phenomenon that may be common among well-studied species. We used pedigree data from nearly 20000 individuals to infer the inheritance of hindwing colouration. The evidence supports a single Mendelian locus with two alleles in males: WW and Wy produce the white and yy the yellow hindwing colour. The inheritance could not be resolved in females as their hindwing colour varies continuously with no clear link with male genotypes. Next, we investigated if the male genotype can be predicted from their phenotype by machine learning algorithms and by human observers. Linear discriminant analysis grouped male genotypes with 97% accuracy, whereas humans could only group the yy genotype. Using vision modelling, we also tested whether the genotypes have differential discriminability to humans, moth conspecifics and their bird predators. The human perception was poor separating the genotypes, but avian and moth vision models with ultraviolet sensitivity could separate white WW and Wy males. We emphasize the importance of objective methodology when studying colour polymorphism. Our findings indicate that by-eye categorisation methods may be problematic, because humans fail to see differences that can be visible for relevant receivers. Ultimately, receivers equipped with different perception than ours may impose selection to morphs hidden from human sight.

An aposematic colour-polymorphic moth seen through the eyes of conspecifics and predators : sensitivity and colour discrimination in a tiger moth
Henze, Miriam J.; Lind, Olle; Mappes, Johanna; Rojas Zuluaga, Bibiana; Kelber, Almut (Wiley-Blackwell Publishing Ltd., 2018)Although predation is commonly thought to exert the strongest selective pressure on coloration in aposematic species, sexual selection may also influence coloration. Specifically, polymorphism in aposematic species cannot ... -
Evolution of signal diversity : predator-prey interactions and the maintenance of warning colour polymorphism in the wood tiger moth Arctia plantaginis
Rönkä, Katja (University of Jyväskylä, 2017)Aposematic organisms avoid predation by advertising defences with warning signals. The theory of aposematism predicts warning signal uniformity, yet variation in warning coloration is widespread. The chemically defended ... -
Colour alone matters : no predator generalization among morphs of an aposematic moth
Rönkä, Katja; De Pasqual, Chiara; Mappes, Johanna; Gordon, Swanne; Rojas Zuluaga, Bibiana (Elsevier Ltd., 2018)Local warning colour polymorphism, frequently observed in aposematic organisms, is evolutionarily puzzling. This is because variation in aposematic signals is expected to be selected against due to predators' difficulties ... -
Geographic mosaic of selection by avian predators on hindwing warning colour in a polymorphic aposematic moth
Rönkä, Katja; Valkonen, Janne K.; Nokelainen, Ossi; Rojas, Bibiana; Gordon, Swanne; Burdfield‐Steel, Emily; Mappes, Johanna (Wiley-Blackwell, 2020)Warning signals are predicted to develop signal monomorphism via positive frequency‐dependent selection (+FDS) albeit many aposematic systems exhibit signal polymorphism. To understand this mismatch, we conducted a large‐scale ...
