Data from: Evolutionary change in flight-to-light response in urban moths comes with changes in wing morphology
<p>Moths and other insects are attracted by artificial light sources. This flight-to-light behaviour disrupts their general activity focused on finding essential habitat resources, such as mating partners, and increases predation risk. It thus has substantial fitness costs. In illuminated urban areas, spindle ermine moths <em>Yponomeuta cagnagella</em> were reported to have evolved a reduced flight-to-light response. Yet, the specific mechanism remained unknown, and was hypothesized to involve either changes in visual perception or general flight ability or overall mobility traits. Here, we test whether spindle ermine moths from urban and rural populations—with known differences in flight-to-light response—differ in flight-related morphological traits. Urban individuals were found to have on average smaller wings than rural moths, which in turn correlated with a lower probability of being attracted to an artificial light source. Our finding supports the reduced mobility hypothesis, which states that reduced mobility in urban areas is associated with specific morphological changes in the flight apparatus.</p>
Body and wing morphology, flight metabolic rates, and wingbeat frequencies for 13 stingless bee species
<p><span>Understanding the effect of body size on flight costs is critical for development of models of aerodynamics and animal energetics. Prior scaling studies that have shown that flight costs scale hypometrically have focused primarily on larger (> 100 mg) insects and birds, but most flying species are smaller. We studied the flight physiology of thirteen stingless bee species over a large range of body sizes (1-115 mg). Metabolic rate during hovering scaled hypermetrically (scaling slope = 2.11). Larger bees had warm thoraxes while small bees were nearly ecothermic; however, even controlling for body temperature variation, flight metabolic rate scaled hypermetrically across this clade. Despite having a lower mass-specific metabolic rate during flight, smaller bees could carry the same proportional load. Wingbeat frequency did not vary with body size, in contrast to most studies that find wingbeat frequency increases as body size decreases. Smaller stingless bees have greater relative wing surface area which may help them reduce the energy requirements needed to fly. Further, we hypothesize that the relatively larger heads of smaller species may change their body pitch in flight. Synthesizing across all flying insects, we demonstrate that the scaling of flight metabolic rate changes from hypermetric to hypometric at approximately 58 mg body mass with hypermetic scaling below (slope=1.2) and hypometric scaling (slope=0.67) above 58 mg in body mass. The reduced cost of flight likely provides selective advantages for the evolution of small body size in insects. The biphasic scaling of flight metabolic rates and wingbeat frequencies in insects supports the hypothesis that the scaling of metabolic rate is closely related to the power requirements of locomotion and cycle frequencies.</span></p>

Phylogenomics and deep convergence in cockroach hind-wing morphology
<p>Despite regular advances in Blattodea systematics, several relationships remain controversial or untested in formal phylogenetic reconstructions. This common situation for understudied metazoan groups limits our power to answer questions about phenotypic evolution. In this study, we infer the evolutionary history of Blattodea using newly sampled taxa that improve phylogenetic resolution while also illuminating the evolutionary history of an unusual phenotype—the apically folded hind-wing. Taxa newly sequenced include those with a hind-wing apical fold (<em>Anaplecta pulchella, A. pygmaea, A. </em>sp<em>. </em>cf<em>. malaysensis, Diplopterina parva, Prosoplecta semperi, Anaplectoidea klossi, </em>and<em> Oulopteryx illuminata</em> sp. nov. that we describe herein, including its male genitalia) and other rare taxa (<em>Dipteretrum</em> <em>hamstroemi</em>, <em>Duchailluia</em> <em>togoensis</em>, <em>Lauraesilpha</em> <em>mearetoi</em>, <em>Buboblatta</em> <em>vlasaki</em>). The phylogenetic design utilizes 41 genes over 91 species in total, analyzed in a maximum likelihood and coalescent framework. To quantify the phylogenetic uncertainty of the analysis, support for various topologies is assessed. We find unambiguous support for the surprising position of Neotropical <em>Oulopteryx</em> (Oulopterygidae) as sister to New Caledonian/Australian Tryonicidae. This, and other phylogenetic findings, reveal that the apically folded hind-wing may have arisen nine times in Blattodea. Further investigations are needed, notably with an increased taxonomic sampling, to demonstrate stronger support for the placement of rogue taxa (e.g., <em>Anaplecta</em>) and to investigate the evolutionary correlates of wing evolution.</p>
Data for: A novel cricket morph has diverged in song and wing morphology across island populations
<p class="MsoNormal"><span>Divergence of sexual signals between populations can lead to speciation, yet opportunities to study the immediate aftermath of novel signal evolution are rare. The recent emergence and spread of a new mating song, purring, in Hawaiian populations of the Pacific field cricket (<em>Teleogryllus oceanicus</em>) allows us to investigate population divergence soon after the origin of a new signal. Male crickets produce songs with specialized wing structures to attract mates from afar (calling) and entice them to mate when found (courtship). However, in Hawaii, these songs also attract an eavesdropping parasitoid fly (<em>Ormia ochracea</em>) that kills singing males. The novel purring song, produced with heavily modified wing morphology, attracts female crickets but not the parasitoid fly, acting as a solution to this conflict between natural and sexual selection. We've since observed increasing numbers of purring males across Hawaii. In this integrative field study, we investigated the distribution of purring and the proportion of purring males relative to other morphs in six populations on four islands and compared a suite of phenotypic traits (wing morphology, calling song, and courtship song) that make up this novel signal across populations of purring males. We show that purring is found in varying proportions across five, and is locally dominant in four, Hawaiian populations. We also show that calling songs, courtship songs, and wing morphology of purring males differ geographically. Our findings demonstrate the rapid pace of evolution in island populations and provide insights into the emergence and divergence of new sexual signals over time.</span></p>
