Most recent outdoor records of two micromoth species- (Lepidoptera: Crambidae, Tortricidae), pests of ornamental plants

Abstract

Two male specimens of Duponchelia fovealis ZELLER, 1847 (Lepidoptera; Crambidae) were collected at lamplight at the turn of August-September 2019 in a suburban area of Budapest (21st district, Csepel). Later, in September 2020, two further male specimens were taken there. In June 2020, a mass outbreak of Cacoecimorpha pronubana (HÜBNER, 1799) (Tortricidae) was observed in the downtown of Budapest (Kálvin square), with males flying around the ornamental Berberis candidula SCHNEID. bushes, not later than 8:00 a.m. In August, a couple of males were still present in the locality. This is the second outdoor observation for C. pronubana in Hungary. Moreover, it is the first finding of any adult, plus the first observation of abundant presence of this species. For D. fovealis, these are the first data of outdoor occurrences in two subsequent years at the same locality. Both species are potentially harmful pests of ornamental plants but overwintering outdoors in Hungary is still not verified. Voucher specimens of both species are deposited in the Hungarian Natural History Museum.
