The meadow spittlebug, Philaenus spumarius (L.) (Hemiptera, Aphrophoridae) is a widespread insect species in the Holarctic region, exhibiting a dorsal colour balanced polymorphism. In the Azores the species is known from high elevations in Terceira and São Miguel islands. A sample of 235 individuals from Pico da Vara and Graminhais protected areas (São Miguel, Azores) (between 645 and 935 m a.s.l.), collected in 2000 and 2017, showed a remarkable high frequency of the melanic morphs flavicollis (FLA) and quadrimaculatus (QUA). In addition, a high frequency of melanics was observed in males. We explore the hypotheses for the origin of Azorean colonization and for the high proportion of melanism in the Azorean populations.

Abstract Background Colour polymorphisms are common among animal species. When combined with genetic and ecological data, these polymorphisms can be excellent systems in which to understand adaptation and the molecular changes underlying phenotypic evolution. The meadow spittlebug, Philaenus spumarius (L.) (Hemiptera, Aphrophoridae), a widespread insect species in the Holarctic region, exhibits a striking dorsal colour/pattern balanced polymorphism. Although experimental crosses have revealed the Mendelian inheritance of this trait, its genetic basis remains unknown. In this study we aimed to identify candidate genomic regions associated with the colour balanced polymorphism in this species. Results By using restriction site-associated DNA (RAD) sequencing we were able to obtain a set of 1,837 markers across 33 individuals to test for associations with three dorsal colour phenotypes (typicus, marginellus, and trilineatus). Single and multi-association analyses identified a total of 60 SNPs associated with dorsal colour morphs. The genome size of P. spumarius was estimated by flow cytometry, revealing a 5.3 Gb genome, amongst the largest found in insects. A partial genome assembly, representing 24% of the total size, and an 81.4 Mb transcriptome, were also obtained. From the SNPs found to be associated with colour, 35% aligned to the genome and 10% to the transcriptome. Our data suggested that major loci, consisting of multi-genomic regions, may be involved in dorsal colour variation among the three dorsal colour morphs analysed. However, no homology was found between the associated loci and candidate genes known to be responsible for coloration pattern in other insect species. The associated markers showed stronger differentiation of the trilineatus colour phenotype, which has been shown previously to be more differentiated in several life-history and physiological characteristics as well. It is possible that colour variation and these traits are linked in a complex genetic architecture. Conclusions The loci detected to have an association with colour and the genomic and transcriptomic resources developed here constitute a basis for further research on the genetic basis of colour pattern in the meadow spittlebug P. spumarius.

We present the complete mitochondrial genome sequence of the meadow spittlebug Philaenus spumarius (Auchenorrhyncha: Cercopoidae). This contribution represents the second mitochondrial genome from the Hemiptera and the second of the three hemipteran suborders sampled. The genome is a circular molecule of 16 324 bp with a total A+T content of 77.0% and 76.7% for coding regions only. The gene content, order, and structure are consistent with the Drosophila yakuba genome structure (Clary and Wolstenholme 1985) and the hypothesized ancestral arthropod genome arrangement (Crease 1999). Nucleotide composition and codon usage are near the means observed in other insect mitochondria sequenced to date but have a higher A+T richness compared with the other hemipteran example, the kissing bug Triatoma dimidiata (Dotson and Beard. 2001. Insect Mol. Biol. 10: 205–215). The major noncoding region (the A+T rich region or putative control region) between the small ribosomal subunit and the tRNAIle gene includes two extensive repeat regions. The first repeat region includes 19 tandem repeats of a 46-bp sequence, whereas the second contains a longer sequence (146 bp) tandemly repeated four times.Key words: mitochondrial genomics, phylogeny, molecular evolution, sequence variation, spittlebug.
