Distribution and Decline of Bradyporus dasypus (Illiger, 1800) (Orthoptera: Tettigoniidae) in Serbia and the Republic of Macedonia

Abstract

Bradyporus dasypus (ILLIGER, 1800) is known to inhabit the eastern parts of the Balkan Peninsula but the knowledge on its distribution is largely based on old literature. In Serbia, we could not confirm this cricket from localities reported during the previous centuries. It probably demises here, limiting the range to only a few recent populations in the southernmost parts of the country. The distribution of this species is better understood in the Republic of Macedonia where the historical distribution roughly matches the recent one. Bradyporus dasypus is known from natural steppe, mixture of forests and steppe, and semi-natural habitats. A strong decline started from the north and was likely caused by increased human activity, changes in agricultural practices and overall habitat deterioration. This resulted in species extinction from Hungary and its listing as Endangered (EN) in Serbia. We suggest that this insect should receive greater conservation importance in the near future.
