Two species of Tineidae: Monopis weaverella (Scott) and Niditinea piercella (Bent.), and three species of Tortricidae: Aethes margarotana (Dup.), Lobesia abscisana (Doubl.) and Foveifera hastana (Hbn.) are new to the Polish fauna. For another tortricid moth - Cydia oxytropidis (Mart.) - first reliable record from Poland is given. M. weaverella (Scott) was reared from pellets of Bubo bubo (L.) and Asio otus (L.), while N. piercella (Bent.) from nests of Sturnus vulgaris L. and Parus major L.
The paper presents data on the distribution of 24 species of tineid moths in Poland. The data were obtained based on a few methods of collecting of moths, mainly with use of artificial light and rearing of adults from decaying wood and bracket fungi inhabited by larvae. Nearly a dozen of species were recorded from particular regions of Poland for the first time. The study also revealed the new aspects of biology and ecology of a few species.
Review of literature data as well as new distributional records of the relict and endangered saproxylic tineid moth Scardia boletella (Fabricius, 1794) in Poland are presented. Unpublished museal data from 1954 to 1963 and own observations from 1988 to 2014, mainly from Bieszczady Mts, East Beskid, Masurian Lake District, Białowieża Forest and Podlasie are included. The species is recorded for the first time from Lublin Upland.
New data are given on 64 species of 22 Microlepidoptera families (excluding Tortricidae) for the province of Pomerania (northern Poland). 40 of these species have been recorded in this region for the first time in over 100 years.
