Beetles (Coleoptera) of the Rogów region. Part III – carrion beetles (Silphidae)

In the present, the third part of the series titled “Beetles (Coleoptera) of the Rogów region” presents a family of carrion beetles (Silphidae), as one of the better-known families of beetles occurring in the Rogów area. The faunistic data of presented species enriched by bionomical information.

The following is a list of the species of carrion beetles that occur in the Rogów region.Almost all species have been collected by the author, and a small part of specimens comes from the collection of J. Dominik, A. Szujecki and S. Mazur.Specimens of evidence are in the collection of Department of Forest Protection and Ecology in Rogów.Names are taken from the Catalogue of Palearctic Coleoptera (Löbl & Smetana 2004).All species have been identified or verified by the author of the work.

Necrodes littoralis
Quite common species usually found on carrion of larger animals.
For the first time in the Rogów region shown by Byk & al. (2013).In the Rogów region very common species, collected on the dead small and big animals and slugs.

CONCLUSIONS
The carrion beetles as ladybirds (Borowski 2015) are one of the better-known families of beetles in the Rogów region.There are 18 known species representing approx.70% of all species in our country.Due to the specific biology of development (on dead animals or their parts) habitat, is of secondary importance, and usually on the carrion we can find several species simultaneously.Given the zoogeographical requirements of some species which are not caught yet from the Rogów area, it is possible to catch two or three more.
