Genomes of skipper butterflies reveal extensive convergence of wing patterns
The genomes of 250 representative species of skippers reveal rampant inconsistencies between their current classification and a genome-based phylogeny, and a dated genomic tree is used to define tribes, overhaul genera, and display convergence in wing patterns that fooled researchers for decades.
Three new subfamilies of skipper butterflies (Lepidoptera, Hesperiidae)
Two genera, Katreus Watson and Ortholexis Karsch, 1895, which are sisters, are well-separated from all other major phylogenetic lineages and originate near the base of the Hesperiidae tree, prior to the origin of some subfamilies.
Fifty new genera of Hesperiidae (Lepidoptera)
Genomic sequencing and analysis of worldwide skipper butterfly (Lepidoptera: Hesperiidae) fauna points to imperfections in their current classification, suggesting two new tribes, two new subtribes and 50 new genera that are named here.
Computed structures of core eukaryotic protein complexes
A coevolution-guided protein interaction identification pipeline that incorporates a rapidly computable version of RoseTTAFold with the slower but more accurate AlphaFold to systematically evaluate interactions between 8.3 million pairs of yeast proteins is developed.
Gypsy moth genome provides insights into flight capability and virus–host interactions
The gypsy moth genome is reported and the genetic features that distinguish gypsy moths from other Lepidoptera are explored, and insights into gene-expression changes of the EGM in response to virus infection are presented, which may assist in the design of viral bioinsecticides.
Structures of core eukaryotic protein complexes
This work uses a combination of RoseTTAFold and AlphaFold to screen through paired multiple sequence alignments for 8.3 million pairs of S. cerevisiae proteins and builds models for strongly predicted protein assemblies with two to five components, and provides structure models spanning almost all key processes in Eukaryotic cells for 104 protein assemblies which have not been previously identified, and 608 which have been structurally characterized.
A genomic perspective on the taxonomy of the subtribe Carcharodina (Lepidoptera: Hesperiidae: Carcharodini)
The obtained whole genome shotgun sequences and phylogenetically analyzed protein-coding regions of representative skipper butterflies from the genus Carcharodus Hübner and its close relatives found that species attributed to four exclusively Old World genera form a monophyletic group that is called a subtribe C archarodina Verity, 1940.
Genomics-guided refinement of butterfly taxonomy.

Analysis of these genome-scale phylogenies projected onto the taxonomic classification and the knowledge about butterfly phenotypes suggests further refinements of butterfly taxonomy that are presented here.
The mitogenome of a Malagasy butterfly Malaza fastuosus (Mabille, 1884) recovered from the holotype collected over 140 years ago adds support for a new subfamily of Hesperiidae (Lepidoptera).
Malaza appears to be an evolutionarily highly distinct ancient lineage, morphologically with several unusual hesperiid features, and the monotypic subfamily Malazinae Lees & Grishin subfam.
Genomics reveals the origins of ancient specimens
The utility of genomics applied to ancient museum specimens is shown to delineate the boundaries of species and populations, and to hypothesize about genotypic determinants of phenotypic traits.
