Skoltech researchers have shown genes involved in embryonic development to be at work in pupation—the drastic transformation that butterflies and some other insects undergo as their larvae mature. The discovery furthers our understanding of the pupal stage, whose evolutionary origins and genetic mechanisms are not entirely clear to this day. The study is published in Scientific Reports.
