It has been suggested that the white coloration of Pieridae butterflies is a warning signal and therefore all white Pieridae could profit from a mimetic resemblance. We tested whether green-veined white (Pieris napi) and orange-tip (Anthocharis cardamines) butterflies benefit from white coloration. We compared their relative acceptability to wild, adult pied flycatchers (Ficedula hypoleuca) by offering live A. cardamines and P. napi together with two non-aposematic butterflies on the tray… 

Yellow and the Novel Aposematic Signal, Red, Protect Delias Butterflies from Predators

It is observed that yellow and red colours appear almost exclusively on the ventral wing surfaces, and that basal lineages have mostly yellow, white, and black wings, whereas derived lineages contain red colour in addition to the other colours.

Müllerian mimetic radiation of Delias butterflies (Lepidoptera: Pieridae) in Bali and Timor

The result suggests that the three mimicry rings of Delias species in Bali and Timor are Müllerian rather than Batesian, which is suggested to have emerged through the convergent evolution and phylogenetic constraints of wing color patterns.

European checkerspots (Melitaeini: Lepidoptera, Nymphalidae) are not aposematic – the point of view of great tits (Parus major)

Checkerspots (Melitaeini, Nymphalidae, Lepidoptera) are usually considered a textbook example of aposematic butterflies and several studies on Nearctic species confirm this; therefore the efficiency of secoiridoids in the chemical protection of butterflies is discussed.

Colours as aggregation signals in Lepidoptera: Are Heliconius Müllerian mimics?

It is proposed that striking colourations may have evolved in some species to improve visibility to conspecifics, even if it also increases visibility to predators and even if colouration provides no other benefit, merely because the improved visibility increases the probability of being part of a cluster which provides protection against predation through dilution.

Inter-species variation in unpalatability does not explain polymorphism in a mimetic species

This study demonstrates that the origin of polymorphic mimicry in H. numata is unlikely to stem from low unpalatability and raises new questions on defence variation within mimetic communities.

Hypothesis: The coloration of the red-black shieldbug has a warning function. This quality can be lowered when the shieldbug is presented on a fragmented background. Organism: We offered

In the Eyes of the Beholders: Female Choice and Avian Predation Risk Associated with an Exaggerated Male Butterfly Color

Evidence is provided that more chromatic male cabbage white butterflies (Pieris rapae) are more attractive to females but should also be more conspicuous to predators, and models of avian color vision suggest that preferred males should beMore conspicuous to known avian predators.

Growth and reproductive costs of larval defence in the aposematic lepidopteran Pieris brassicae.

A clear life-history cost of an antipredator defence in a model pest species is demonstrated and the expected relationship between female body size and potential fecundity can be disrupted and is shown to be disrupted.

What constitutes optical warning signals of ladybirds (Coleoptera: Coccinellidae) towards bird predators: colour, pattern or general look?

The results obtained in the present study suggest the high importance of the spotted pattern as well as general appearance in the ladybird recognition process.



Predation, thermoregulation, and wing color in pierid butterflies

It is suggested that Pieris butterflies are relatively unpalatable to visual predators, supporting the idea that the white wing pigment of Pieris represents aposematic coloration, and the degree of palatibility may vary among Pieris species.

Palatablility and escaping ability in Neotropical butterflies: tests with wild kingbirds (Tyrannus melancholicus, Tyrannidae)

Results indicate that the learning process in kingbirds may demand a large mortality in prey populations, even among species generally accepted as unpalatable and aposematic, and support the assertion that escaping ability and unpalatability evolved in butterflies as alternative strategies to avoid predation by birds.

Batesian mimicry without distastefulness?

Lindroth's hypothesis, which suggests that the flea-beetle, which can escape suddenly from its exposed position on the food-plant by jumping, acts as a model and Lebia as a relatively sluggish mimic, is proposed.

Resource partitioning among a flycatcher guild in Finland

The sexes of the redstart and the pied flycatcher differed in foraging sites, males having the wider niches, and most of the differences between the species can be explained in terms of the use of the three macrosubstrate categories.

Flight morphology of Neotropical butterflies: palatability and distribution of mass to the thorax and abdomen

Differences between the sexes in mass distribution suggest differences in reproductive constraints and predation stress in Neotropical butterflies.

Hidden colour aversions in domestic chicks triggered by pyrazine odours of insect warning displays

This study demonstrates, in prey choice experiments with birds, that pyrazine interacts with red and yellow to induce strong aversions to these aposematic colours that are not shown in the absence of the odour.

The biological roles of pyrazines: evidence for a warning odour function

It is demonstrated that naive hatchling chicks, when offered drinking water to which 2-methoxy-3-isobutylpyrazine is added, develop a neophobic ‘alerting’ reaction, which suggests that birds, a major group of insect predators, can interpret pyrazines as alerting or warning signals.

Novelty effects in a multimodal warning signal

Pyrazine novelty has been an important pressure in the evolution of multimodal warning signals, and can continue to promote the avoidance of warningly coloured food, even when it is relatively familiar.

The scent scale substances of malePieris butterflies (Pieris melete andPieris napi)

The present chemotaxonomic approach shows the 2 species of Pieris to be distinct.

Protean defence by prey animals

A number of poorly understood behavioural aspects of the ecology of predator-prey relationships are united in a single theory, evidence that protean displays operate by arousing neurological conflict, thereby delaying the predator's reactions and reducing the effectiveness of predatory mechanisms.
