Wing color and pattern variations in the Turkish population of Ypsolopha ustella (Clerck, 1759) on oak and some additional notes (Lepidoptera, Ypsolophidae)

The genus Ypsolopha Latreille, [1796] is known with 21 species in Türkiye. Known records are generally based on a few faunistic studies limited to a few provinces and there are almost no studies on their biology. In this study, the Turkish populations of Ypsolopha ustella (Clerck, 1759) were evaluated for the first time. Larvae of the species, whose faunistic record is known only from Ankara province in Türkiye, collected from the oak forest of Beypazarı district, were examined. Larvae collected from Quercus pubescens Willd were fed with laeves of host plants in the laboratory. All larvae entered the pupal stage. The pupal stage lasted an average of 18 days. Its larval, pupal and adult stages were described and photographed. Wing colors and pattern variations of adult moths were presented.
