A dated phylogeny of evolutionary relationships among major insect taxonomic groups with the availability of genomic resources for each lineage overlaid. The size of each circle represents the number of available nuclear genomes and their color corresponds to life history strategy, either terrestrial (red) or aquatic (blue). To the right of the tree, the number of described species per group are shown on a log10 scale. Groups that include both terrestrial and aquatic species (e.g., Collembola) are in black font with diversity given separately for terrestrial (red) and aquatic (blue) species. Mosquitoes (genomes and species; Order Diptera) were not included in the analysis. Yellow stars indicate the number of chromosome-level assemblies for a given lineage with a contig N50 > 1 million base pairs (there are none for aquatic insects). Species numbers were sourced from a combination of studies [1,2,11,16,17,18,19,20] and the figure was modified from [21]. Complete information for genome availability is provided in Table S1.
