Improvements in reference genome generation for insects and across the tree of life are extending the concept and utility of model organisms beyond traditional laboratory-tractable supermodels. Species or groups of species with comprehensive genome resources can be developed into model systems for studying a large variety of biological phenomena. Advances in sequencing and assembly technologies are supporting these emerging genome-enabled model systems by producing resources that are increasingly accurate and complete. Nevertheless, quality controls including assessing gene content completeness are required to ensure that these data can be included in expanding catalogues of high-quality references that will greatly advance understanding of insect biology and evolution.
