Contributions to the fauna of Türkiye Geometridae

Abstract

The Geometridae is one of the most populous families in terms of the number of species in the order Lepidoptera. It is known to have more than 23,000 species worldwide. Geometridae species cause damage to forest trees, but it has been reported that they also cause damage to cultivated plants in studies. This research was carried out in Turkey's Central Black Sea Region (Amasya, Çorum, Ordu, Samsun, Sinop, Tokat, and Yozgat) in 2017 and 2018 years. Adult specimens of Geometridae were collected using an insect net and a light trap in the study region. Obtained specimens were prepared according to standard museum methods for butterflies and prepared genitalia structures. As a result of the study, five subfamilies (Ennominae, Geometrinae, Larentiinae, Orthostixinae, Sterrhinae), 36 genera, and 48 species were determined. Also in this paper, the examined materials and adult photographs of the species are given. This study provides new information about the zoogeographic distribution of Geometridae species identified in the research area.
