From: Evolution of wing scales in Diptera documented by fossils
Development of scale cover in wings of fossil Diptera. Dipteran families with scaled wings through epochs; representative species preserved in fossil resins. Basic shapes accompany relevant wings; width of lower costal fringe is proportional to wing size. A, B, Burmaculex antiquus, costal fringe preserved fragmentarily in two females (Burmaculicinae); C, Burmaculex burmanicus; D, Paleoculicis minutus; E, Cocquilletidia sp.; F, Culex malariager; G, Culex pipiens; H, Corethrella andersoni; I, Corethrella miocaenica; J, Corethrella prisca; K, Corethrella kipferi; L, Corethrella oppositophila (K, L, recent representatives of Corethrellidae with costal fringe only and with veins covered with scales, respectively); M, Maietta hoffeinsetta, sp. nov.; N, Maietta trimedia. Chronology axis is not to geological scale
