“…In this study we measured the ANI among several butterfly and moth species and found that Pieris species share relatively high sequence identities in comparison to the other lepidopterans. P. brassicae and P. rapae are closely related species, having a similar geographical distribution and host-plant range, but differ in their oviposition strategy and their larval feeding behavior ( Feltwell, 1982 ; Davies and Gilbert, 1985 ; Ryan et al, 2019 ). Here, we identified 60 PbraORs , 31 PbraIRs , and 39 PbraGRs from the P. brassicae genome and 60 PrapORs , 34 PrapIRs , and 39 PrapGRs from the P. rapae genome by searching against genomes with lepidopteran homologs.…”

“…The cabbage white butterflies, Pieris spp., are important model species with regards to the co-evolutionary arms-race with their host plants, their natural enemies and their adaptations to novel environments ( Edger et al, 2015 ; Sikkink et al, 2017 ; Zhu F. et al, 2018 ; Okamura et al, 2019 ). Pieris brassicae and P. rapae are very closely related species sharing comparable appearances, host plants and geographical distributions ( Feltwell, 1982 ; Ryan et al, 2019 ; EPPO, 2022 ). Both species have characterized chemosensory systems and are able to detect similar volatiles and tastants in their environment ( van Loon et al, 1992a ; Miles et al, 2005 ).…”

Sensory processes have often been argued to play a central role in the selection of ecological niches and in the formation of new species. Butterflies are among the best studied animal groups with regards to their evolutionary and behavioral ecology and thereby offer an attractive system to investigate the role of chemosensory genes in sympatric speciation. We focus on two Pieris butterflies with overlapping host-plant ranges: P. brassicae and P. rapae. Host-plant choice in lepidopterans is largely based on their olfactory and gustatory senses. Although the chemosensory responses of the two species have been well characterized at the behavioral and physiological levels, little is known about their chemoreceptor genes. Here, we compared the chemosensory genes of P. brassicae and P. rapae to investigate whether differences in these genes might have contributed to their evolutionary separation. We identified a total of 130 and 122 chemoreceptor genes in the P. brassicae genome and antennal transcriptome, respectively. Similarly, 133 and 124 chemoreceptors were identified in the P. rapae genome and antennal transcriptome. We found some chemoreceptors being differentially expressed in the antennal transcriptomes of the two species. The motifs and gene structures of chemoreceptors were compared between the two species. We show that paralogs share conserved motifs and orthologs have similar gene structures. Our study therefore found surprisingly few differences in the numbers, sequence identities and gene structures between the two species, indicating that the ecological differences between these two butterflies might be more related to a quantitative shift in the expression of orthologous genes than to the evolution of novel receptors as has been found in other insects. Our molecular data supplement the wealth of behavioral and ecological studies on these two species and will thereby help to better understand the role of chemoreceptor genes in the evolution of lepidopterans.

A checklist of European butterfly larval foodplants

Butterflies are charismatic insects and have been well studied, particularly in Europe. They are disproportionately used in generating and testing hypotheses; on everything from general evolutionary processes, such as speciation or host association dynamics; to conservation‐related studies, such as climate change or habitat loss. Accurate lists of the larval foodplants for European butterflies are not readily available. Mistakes are propagated and information cannot be checked for accuracy. The level of evidence is unknown, and how usage varies between countries is poorly understood. The study consulted 1119 references to produce 19,488 records of larval foodplants for European butterflies. This resulted in 5589 larval host plant records for 464 European butterfly species, with multiple references, enabling information to be checked. Information was unavailable for 59 species. The level of evidence for each relationship shows the current state of knowledge. Significant issues were identified for 3.9% of records extracted from references due to mistakes, ambiguous or unknown plant names, distribution issues, resulting in information being lost. Plants with questionable distributions suggest either mis‐identification or species that have been split. Little is known about plant usage in Eastern Europe. The larval foodplants of many monophagous and Satyrinae butterflies are poorly studied. Only 63% of threatened 2010 Red Listed butterflies have reliable host plant records. The study has provided ecologists with a valuable resource, of a more accurate checklist of the larval foodplants for each European country. Why plant usage varies over a butterfly's distribution opens up some interesting research questions.
