Evolution of genes families and estimated completeness of the gene sets of 14 insect species. A The species’ ultrametric tree was adapted from Mckenna et al. [20]. We used CAFE (Computational Analysis of gene Family Evolution) to infer the size change of gene families. This summary tree shows the average expansion/contraction (radius of node circles), where for each circle, purple highlights the percentage of expanded gene families, and green highlights the percentage of contracted gene families. B Completeness of offcial gene sets of each insect species were assessed by applying the Benchmarking Universal Single-Copy Orthologs (BUSCO, Insecta set) pipeline
