Grasshoppers and crickets (Orthoptera), earwigs (Dermaptera) and cockroaches (Blattodea) of the Bory Tucholskie National Park (Poland)

Abstract

This paper presents the results of the study on grasshoppers and crickets (Orthoptera), earwigs (Dermaptera) and cockroaches (Blattodea) of the Bory Tucholskie National Park (=BTNP) (part of Tuchola Forest, northern Poland), conducted in the years 2001, 2013 and 2014. The insects were caught using Moericke traps at 9 sites, capturing respectively: 2001 – 11 ind., 2013 – 1115 ind. and 2014 – 228 ind. An additional visual record was made at the tenth site, where no traps were set. In total, 24 species of grasshoppers and crickets, 3 species of earwigs and 1 species of cockroach were recorded in the BTNP. Tettigonia cantans (Fuessly), Roeseliana roeselii (Hagenb.), Pholidoptera griseoaptera (Deg.), Chelidurella acanthopygia (Géné) and Labidura riparia (Pall.) were found for the first time within the whole Tuchola Forest. The research method used is noteworthy, as the capture of such a large number of orthopteroid insects in Moericke traps is rare in Poland.
