Many cool stories in Runa Ekrem's PhD. Most will revolve around a marine #insect #Clunio marinus - the first one reaching publication status does not. Still, the theme is a related one: how do males and females (moths? butterflies?) time their lives when neither lives very long, and the environment is seasonal? Naturally selected #phenology conflicts with sexual #selection, and if your intuition tells you that #SexualConflict and unmatedness play a role too, you're right! https://academic.oup.com/evolut/advance-article/doi/10.1093/evolut/qpac054/6896158
