SummaryDifferent species of large tropical butterflies belonging to the genus Morpho vary dramatically in both the amount of blue color on their wings and the associated irridescence (reflectance). This paper discusses how such a morphological properties may be related to both courtship behavior and effective means of reducing predation (especially by birds) in the low density adult populations. Essentially, the hypothesis is advanced that territorial species of Morpho can afford to possess… Expand
Convergent morphology and divergent phenology: unravelling the coexistence of mimetic Morpho butterfly species
It is shown that temporal segregation may facilitate the co-existence of closely-related species sharing the same ecological niche, suggesting that phenological shifts may represent an overlooked factor of sympatric speciation. Expand
Convergence in sympatry: Evolution of blue‐banded wing pattern in Morpho butterflies
The results provide support to the existence of escape mimicry in the wild and stress the importance of estimating trait variation within species to understand trait variation between species, and to a larger extent, trait diversification at the macro‐evolutionary scale. Expand
Sexual Size Dimorphism in the Color Pattern Elements of Two Mimetic Heliconius Butterflies
This is the first study specifically concerning quantitative sexual dimorphism in the coloration of this well-known genus of butterflies and it opens new prospects to investigate sex-related natural selection and sexual selection of color pattern elements. Expand
Both Palatable and Unpalatable Butterflies Use Bright Colors to Signal Difficulty of Capture to Predators
It is argued that butterflies may utilize a variety of escape tactics against insectivorous birds and that signaling difficulty of capture to predators is a widespread phenomenon in butterflies, and this ability may not be limited to palatable butterflies. Expand
Hearing in a diurnal, mute butterfly, Morpho peleides (Papilionoidea, Nymphalidae)
It is hypothesize that Vogel's organs in butterflies such as M. peleides have evolved to detect flight sounds of predatory birds, and the evolution and taxonomic distribution of butterfly hearing organs are discussed. Expand
Visual sensitivity in the crepuscular owl butterfly Caligo memnon and the diurnal blue morpho Morpho peleides: a clue to explain the evolution of nocturnal apposition eyes?
SUMMARY Insects active in dim light, such as moths and many beetles, normally have superposition compound eyes to increase photon capture. But there are nocturnal and crepuscular insects – such asExpand
Why are Morpho Blue
Abstract: Their large size and the often brilliant blue of their wings put butterflies from the Morpho genus among some of the most spectacular insects in South America. Often mentioned in theExpand
How does the blue-ringed octopus (Hapalochlaena lunulata) flash its blue rings?
It is suggested that the mechanism of producing iridescent signals has not previously been reported in cephalopods and it is an exceptionally effective way to create a fast and conspicuous warning display. Expand
Interspecific visual signalling in animals and plants: a functional classification

It is proposed that interspecific visual signalling can be divided into six major functional categories: anti-predator, food acquisition, anti-parasite, host acquisition, reproductive and agonistic signalling, with each function enabled by several distinct mechanisms. Expand
What does a butterfly hear? Physiological characterization of auditory afferents in Morpho peleides (Nymphalidae)
It is proposed that the ears of butterflies, like those of many vertebrate prey such as some rabbits and lizards, function primarily in predator risk assessment and are capable of amplitude and frequency discrimination. Expand


Community Ecology of Some Tropical Rain Forest Butterflies
The results of this study indicate that this butterfly community is very stable, both spatially and temporally, which is of interest with respect to current ecological theory on community structure. Expand
The relationship between butterflies and their food plants is investigated, the examination of patterns of interaction between two major groups of organisms with a close and evident ecological relationship, such as plants and herbivores. Expand
The Effect of Experience and Novelty on Avian Feeding Behavior with Reference to the Evolution of Warning Coloration in Butterflies. II. Reactions of Naive Birds to Novel Insects
In this experiment, hand-raised birds avoided novel insects in a manner which showed that the rejection was not learned or innate, and suggest that there need not be an association with noxiousness in order for conspicuous coloration to be a selective advantage. Expand
