In sexual selection, multimodal signals elicit mate choice when more than one sensory modality is activated. However, determining the relative use of each signal is difficult because it requires a comprehensive understanding of the mating system and how this system works under natural conditions. We examined the role of structural ultraviolet (UV) reflectance and pheromones in the butterfly Colias eurytheme. Both traits are important in mediating interspecific interactions and pheromones have…

Multiple signals predict male mating success in the lek-mating lesser prairie-chicken (Tympanuchus pallidicinctus)
TLDR
It is demonstrated that mate choice in lesser prairie-chickens (Tympanuchus pallidicinctus) correlates with male behavior, morphology, skin patch color, and territorial characteristics, a rare demonstration of mating success being influenced by how male behavior changes when females are present or absent.
Ultraviolet Ornamentation and Male Mating Success in a High-Density Assemblage of the Butterfly Colias eurytheme
  • D. Kemp
  • Biology
    Journal of Insect Behavior
  • 2006
TLDR
The density and apparently very young age of individuals in the sampling population may have pre-disposed this result, and thus, how sexual selection on male colouration may operate in a density dependent manner is discussed.
Potential direct fitness consequences of ornament-based mate choice in a butterfly
TLDR
The results do not strongly support the hypothesis that female C. eurytheme prefer bright UV males to obtain direct benefits or to minimize the costs associated with lengthy copulations.
Distance Communication of Sexual Status in the Crayfish Orconectes quinebaugensis: Female Sexual History Mediates Male and Female Behavior
TLDR
Tests of two hypotheses on the role of distance communication in the reproductive behaviors of crayfish suggest that distance chemical communication of sexual status may be particularly advantageous when the costs of mate searching are high.
Female preference for multi-modal courtship: multiple signals are important for male mating success in peacock spiders
TLDR
Evidence for strong sexual selection on males in this jumping spider system is found, with success contingent upon a combination of visual and vibratory displays, and some support for both the redundant signal and multiple messages hypotheses for the evolution of multi-modal signalling is provided.
Female iridescent colour ornamentation in a butterfly that displays mutual ornamentation: is it a sexual signal?
TLDR
A study testing two functional hypotheses for the female UV-reflecting patch: an antiharassment hypothesis and a male mate choice hypothesis, finding that the results provide no support for the antihar harassment hypothesis.
Behaviour before beauty: signal weighting during mate selection in the butterfly Papilio polytes.
TLDR
It is found that males exclusively courted active females, irrespective of female wing pattern, and that male preference for non-mimetic females may play an active role in the maintenance of the non-Mimetic female form in natural populations, where males are likely to be in the presence of active, as well as inactive, mimetic and non-reinforced females.
Female mating biases for bright ultraviolet iridescence in the butterfly Eurema hecabe (Pieridae)
TLDR
Behavioral experiments involving manipulations of ambient light environments and male reflectance patterns with observation of wild mating patterns are couple to investigate visual mating biases in the large grass yellow (Eurema hecabe), finding the presence of a UV signal--based female bias.
A major locus controls a biologically active pheromone component in Heliconius melpomene
TLDR
Using quantitative trait locus (QTL) mapping, a single locus on chromosome 20 is identified responsible for 41% of the parental species’ difference in octadecanal production, suggesting they could be important during speciation.
Beyond magic traits: Multimodal mating cues in Heliconius butterflies
TLDR
Testing for sexual isolation between two closely related species with similar patterns, H. timareta thelxinoe and H. melpomene amaryllis, found a key role for short‐distance cues in determining male choice in H.Timareta males, providing candidate chemical mating cues involved in sexual isolation.

Visual and Chemical Signalling in Butterflies: Functional and Phylogenetic Perspectives
TLDR
The general context of visual and olfactory signals in butterfly communication is discussed using specific examples, including Amauris, and models for the evolution of chemical signalling systems in these mimetic butterflies are compared and assessed.
Ultraviolet reflection and its behavioral role in the courtship of the sulfur butterflies Colias eurytheme and C. philodice (Lepidoptera, Pieridae)
TLDR
The courtship behavior of the sulfur butterflies, Colias eurytheme and C. philodice, was studied in the field and in large outdoor flight cages to investigate the nature of releasers of male Courtship behavior and to determine the basis of conspecific mate recognition by females.
Colour pattern evolution in butterflies: a phylogenetic analysis of structural ultraviolet and melanic markings in North American sulphurs
TLDR
Analysis of the phylogenetic distribution of two elements of male colour pattern – UV reflectance and melanic markings – in North American sulphur butterflies sheds interesting light on the evolution of structural coloration in this group and adds strength to the idea that brilliant male coloration is principally of sexually selected origin.
Female responses to isolated signals from multimodal male courtship displays in the wolf spider genusSchizocosa(Araneae: Lycosidae)
TLDR
It is found that the sensory sensitivities of conspecific females were associated with the predominant modes of male courtship communication and coevolution between male signal design and female sensory design is suggested.
Courtship as an honest indicator of male parental quality in the bicolor damselfish stegastes partitus
TLDR
It is suggested that observed differences between males in their courtship rates and parental ability may be a result of differences in their energy reserves.
The importance of olfactory signals in the gasterosteid mating system: sticklebacks go multimodal
TLDR
It is shown that the nuptial signal is in fact multimodal: male-based olfactory cues also transmit information to receptive females, and three-spined and brook sticklebacks recognized the scent from each other’s males, but discriminated in favour of their own males when asked to choose between conspecific and heterospecific odours.
Sexual cooperation and conflict in butterflies: a male–transferred anti–aphrodisiac reduces harassment of recently mated females
TLDR
It is shown that P. napi males transfer an anti–aphrodisiac to the female at mating, methyl–salicylate (MeS), which is a volatile substance which mated females emit when courted and which makes males quickly abandon them.
Paternity and Multiple Signaling: Effects of a Secondary Sexual Character and Song on Paternity in the Barn Swallow
TLDR
Female barn swallows Hirundo rustica, which are known to prefer males with the longest tail feathers, also preferred males with extreme expressions of a behavioral trait (song rate), as determined from patterns of paternity assessed by microsatellites.
Ultraviolet colours in butterflies: intra- or inter-specific communication?
  • C. Brunton, M. Majerus
  • Biology

  • 1995
TLDR
It is suggested that variation in uv reflectance in male Pierid butterflies is more likely to be associated with mate choice by females or with male-male interactions, and to recognise particular species on the basis of uv colours.
MALE SCENT-PRODUCING STRUCTURES IN Colias BUTTERFLIES Function, Localization, and Adaptive Features
TLDR
It is suggested that in sulfurs the morphology and chemistry of the scent glands along with the behavior of the male are structured in a way that minimizes the evaporative loss of scent from the wings when the male is not courting females.
