Occurrence of Idaea spissilimbaria (Mabille, 1888) in Hungary (Lepidoptera: Geometridae)

Abstract

One male specimen of the rarely collected Idaea spissilimbaria (Mabille, 1888) (Lepidoptera: Geometridae: Sterrhinae), previously only reported from four European countries, came to light on 1 July 2023 at the terrace of a resort in the town of Kőszeg, Western Hungary. The occurrence is the first record from Hungary, and the second record from the Carpathian Basin, as the species has been known from Transylvania (Romania). The collecting site is the northernmost one and it is at the lowest elevation among all known localities of the species.
