Heterozygote advantage and pleiotropy contribute to intraspecific color trait variability. [PDF]
Abstract The persistence of intrapopulation phenotypic variation typically requires some form of balancing selection because drift and directional selection eventually erode genetic variation. Heterozygote advantage remains a classic explanation for the maintenance of genetic variation in the face of selection.

Can multiple-model mimicry explain warning signal polymorphism in the wood tiger moth, Arctia plantaginis (Lepidoptera: Erebidae)? [PDF]
Multiple-model mimicry, whereby different morphs of an aposematic species each resemble another defended species sharing the costs of predator education, has been proposed as a mechanism allowing colour polymorphisms in aposematic species. Male wood tiger moths, Arctia plantaginis (Linnaeus, 1758), are chemically defended and polymorphic (yellow, white)

Are Toxic Butterflies More Easily Detected by Human 'Predators'? [PDF]
Aposematic signals are often thought to be conspicuous and stable across environments. Yet, butterflies can have distinct colours on their dorsal and ventral sides which contradict this prediction. We found that despite toxic butterflies having similar detectability on both sides, only dorsal detectability positively correlated with toxicity.

We investigated the within‐ and between‐population variability in chemical defence of the wood tiger moth (Arctia plantaginis). The major components of its defences, SBMP (2‐sec‐butyl‐3‐methoxypyrazine) and IBMP (2‐isobutyl‐3‐methoxypyrazine), are volatiles that deter bird attacks.

Genetic Variation in Chemical Defence Affects Protection of an Herbivorous Insect Against Predation. [PDF]
ABSTRACT Genetic variation contributes to intraspecific differences in the chemical defence in many insect species, yet the underlying genetic mechanisms remain poorly understood. The horseradish flea beetle, Phyllotreta armoraciae, sequesters glucosinolates from its horseradish host plant and activates them using endogenous myrosinase enzymes.

Predictors of Wing Attacks by Birds Across Australian Butterflies. [PDF]
Predation pressure can vary latitudinally and across different prey communities as well as between males and females of the same prey species. Here, the variation in predation pressure on Australian butterflies was assessed using wing damage caused by bird attacks in over 2310 individuals from five butterfly families.

Don't You Know That I'm Toxic? Wild Birds Learn to Avoid a Novel Aposematic Warning Signal. [PDF]
The foraging behaviours of predators towards aposematic prey have been studied extensively and there is much empirical evidence to support this theory. Often, studies involving wild species are relatively short‐term and so there is a possibility that any aversive behaviours exhibited by predators are merely neophobic. In this study, we ensure predators

Wing phenotypes in butterflies and moths are a striking example of adaptive evolution and are a tractable trait to dissect the genetic mechanisms underlying adaptations. Studies of Lepidoptera, mainly mimetic species from the tropics, have led to two general patterns.

Multimodal Aposematic Signals and Their Emerging Role in Mate Attraction [PDF]
Chemically defended animals often display conspicuous color patterns that predators learn to associate with their unprofitability and subsequently avoid.
