The fauna of Geometrid moths of the Natural Forest Reserve "Cobîleni" Republic of Moldova - Preliminary data

Abstract

Cobîleni Natural Forest Reserve with a surface of 33.5 ha is situated near Lopatna village, Orhei district, on the right bank of the Dniester River. The aim of the study was to assess the geometrid moths (Lepidoptera, Geometridae) fauna from this reserve. The most part of entomological materials from Cobîleni Natural Forest Reserve discussed in this paper were collected at the light trap during vegetation period of 2018. In the paper the list of fifty-five geometrids species is given, also their geographical distribution, ecological and trophic structure. The geometridae species collected from this reserve belong to five subfamilies. Most of the captured specimens belong to the Ennominae subfamily with 36 species, as it is typical for mesophilous meadows, followed by Sterrhinae with nine species, then Larentiinae with eight, and finally Orthostixinae and Geometrinae with only one species each. In the result of establishing of taxonomic affiliation of the entomological material collected during 2018, a new geometrid species for the fauna of the Republic of Moldova was identified: Cyclophora linearia.
