New data on the occurrence and macroptery of Eumodicogryllus bordigalensis (Latreille, 1804) (Orthoptera: Gryllidae) in Poland and in other parts of the species range

Abstract

Abstract A dozen specimens of Eumodicogryllus bordigalensis were found in three localities in Poland as well more than thirty foreign specimens of the species collected in southern Europe, the Caucasus and Mongolia. They are deposited in the collection of the Museum of Zoology PAS. The adult specimens were studied in detail and measured. The indigenous specimens and the majority of the foreign ones proved to be macropterous. The problems of wing polymorphism and the possibilities of migration are discussed.
