New faunistic and host records of Lepidoptera from Poland, with Stigmella naturnella (Klimesch, 1936) reported for the first time

New records of eleven rare species of Lepidoptera are given from Poland. Stigmella naturnella (KLIMESCH, 1936) (Nepticulidae) has been recorded in Poland for the first time. Surprisingly, this nepticulid was found in an artificial ecosystem - a city park. The occurrence of Scrobipalpula tussilaginis (FREY, 1867) and Ephysteris inustella (ZELLER, 1847) in Poland has been confirmed after over a century. Salix caprea L. is given as the first reliable record of a host plant for the larva of Teleiodes flavimaculella, and Betula pubescens EHRH. is found to be a new host plant of Stigmella naturnella.
