TL;DR: Basking at low Ta allowed the maintenance of higher thoracic temperatures than could be maintained in continuous flight, and the butterflies then adopted a sit-and-wait strategy in mate chasing, and at high T they used a search strategy for mate seeking instead.
Abstract: The inornate ringlet butterfly, Coenonympha inornata, is highly constrained by tem- perature in its activity, and even on sunny days may spend a major portion of its time grounded. Thermoregulation in these lateral baskers can consume the major portion of their time; males alternate between basking and flying, and at 1 6WC spend 73% of their time basking and only 27% of their time flying. At high ambient temperatures (Ta), on the other hand, they spend most (> 80%) of their time in flight. Active butterflies were followed for up to 52 min in the field to determine foraging behavior, mating success, and time investments for thermoregulation. Foraging was a minor component of their flight activity. Most of the flight activity was associated with mate-seeking. Thoracic temperatures were measured in the field on individuals tethered to thermocouples that permitted flight and basking behavior. Basking at low Ta allowed the maintenance of higher thoracic temperatures than could be maintained in continuous flight, and the butterflies then adopted a sit-and-wait strategy in mate chasing. In contrast, at high T. they used a search strategy for mate seeking instead.

TL;DR: Analysis of the past and current patterns of hybridization and divergence within a complex of closely related butterflies in the genus Coenonympha suggests a potential role for ecological drivers during their speciation processes.
Abstract: Until complete reproductive isolation is achieved, the extent of differentiation between two diverging lineages is the result of a dynamic equilibrium between genetic isolation and mixing. This is especially true for hybrid taxa, for which the degree of isolation in regard to their parental species is decisive in their capacity to rise as a new and stable entity. In this work, we explored the past and current patterns of hybridization and divergence within a complex of closely related butterflies in the genus Coenonympha in which two alpine species, C. darwiniana and C. macromma, have been shown to result from hybridization between the also alpine C. gardetta and the lowland C. arcania. By testing alternative scenarios of divergence among species, we show that gene flow has been uninterrupted throughout the speciation process, although leading to different degrees of current genetic isolation between species in contact zones depending on the pair considered. Nonetheless, at broader geographic scale, analyses reveal a clear genetic differentiation between hybrid lineages and their parental species, pointing out to an advanced stage of the hybrid speciation process. Finally, the positive correlation observed between ecological divergence and genetic isolation among these butterflies suggests a potential role for ecological drivers during their speciation processes.

TL;DR: In this study, virgin females of the shorter-lived C. tullia seemed to be in greater urgency to mate and courtships more often resulted in copulation than in C. pamphilus.

TL;DR: The concordance of life history with genetic and morphological variation suggests that differences between unIVoltine and bivoltine populations are maintained by selection.
Abstract: Range expansion by the North American butterfly species Coenonympha tullia is associated with dramatic changes in life history and in genetic and morphological variation. Eight of ten independent, variable loci exhibit step-clines in allele frequency; step-clines also occur in four wing pattern characters. Populations from the old part of the range are univoltine, and have significantly less genetic and morphological variation than populations from the recently colonized ranger, which arc bivoltine. The concordance of life history with genetic and morphological variation suggests that differences between univoltine and bivoltine populations are maintained by selection. Increased electrophoretic variation in the recently colonized range may have arisen by selection on rare variants within the old part of the range.
