Natural selection generally favours phenotypic variability in camouflaged organisms, whereas aposematic organisms are expected to evolve a more uniform warning coloration. However, no comprehensive analysis of the phenotypic consequences of predator selection in aposematic and cryptic species exists. Using state-of-the-art image analysis, we examine 2800 wing images of 82 moth species accessed via three online museum databases. We test whether anti-predator strategy (i.e., camouflage or aposematism) explains intraspecific variation in wing colour and pattern across northern hemisphere moths. In addition, we test two mutually non-exclusive, ecological hypotheses to explain variation in colour pattern: diel-activity or dietary-niche. In this work, taking into account phylogenetic relationships, moth phenotypic variability is best explained by anti-predator strategy with camouflaged moths being more variable in wing patterning than aposematic species.

A synthesis of deimatic behaviour
Drinkwater, Eleanor; Allen, William L.; Endler, John A.; Hanlon, Roger T.; Holmes, Grace; Homziak, Nicholas T.; Kang, Changku; Leavell, Brian C.; Lehtonen, Jussi; Loeffler‐Henry, Karl; Ratcliffe, John M.; Rowe, Candy; Ruxton, Graeme D.; Sherratt, Tom N.; Skelhorn, John; Skojec, Chelsea; Smart, Hannah R.; White, Thomas E.; Yack, Jayne E.; Young, Catherine M.; Umbers, Kate D. L. (Wiley, 2022)Deimatic behaviours, also referred to as startle behaviours, are used against predators and rivals. Although many are spectacular, their proximate and ultimate causes remain unclear. In this review we aim to synthesise ... -
Social transmission in the wild can reduce predation pressure on novel prey signals
Hämäläinen, Liisa; Hoppitt, William; Rowland, Hannah M.; Mappes, Johanna; Fulford, Anthony J.; Sosa, Sebastian; Thorogood, Rose (Nature Publishing Group, 2021)Social transmission of information is taxonomically widespread and could have profound effects on the ecological and evolutionary dynamics of animal communities. Demonstrating this in the wild, however, has been challenging. ... -
Predator selection on multicomponent warning signals in an aposematic moth
Hämäläinen, Liisa; Binns, Georgina E.; Hart, Nathan S.; Mappes, Johanna; McDonald, Paul G.; O’Neill, Louis G.; Rowland, Hannah M.; Umbers, Kate D. L.; Herberstein, Marie E. (Oxford University Press (OUP), 2023)Aposematic prey advertise their unprofitability with conspicuous warning signals that are often composed of multiple color patterns. Many species show intraspecific variation in these patterns even though selection is ... -
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 ...
