Beetles (Coleoptera) of the Rogów region. Part II – ladybirds (Coccinellidae)

In the present, the second part of the series titled “Beetles (Coleoptera) of the Rogów region” presents a family of ladybirds (Coccinellidae), as one of the better-known families of beetles occurring in the Rogów area. The faunistic data of presented species enriched by bionomical informations. In addition, the study showed a new species of ladybird for the Polish fauna and it is Nephus (B.) bisignatus (Boh.).


INTRODUCTION
Until now from the Rogów region has been reported 29 species of ladybirds (Borowski 2001). In terms of number of species of beetles individual families occurring in the Rogów region, ladybirds family has occupied 7th place. This condition is undoubtedly the work of M. Nunberg (1986), in which it has 26 species of ladybirds. Of this group, only three species were previously reported (Wiąckowski 1957, Szujecki & Zaborowski, 1968. Two more species were reported in 1999, from the "Zimna Woda" reserve (Borowski & Kieszek 1999), located in the "Zimna Woda and Wilczy Dół" range. The last one shown .
The following is a list of the species of ladybirds 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 M. Nunberg, and A. Szujecki. 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 2007). All species have been identified by the author of the work, and most of the determined specimens was verified by Andrzej Jadwiszczak. (Linnaeus, 1758) For the first time in the Rogów region shown by Szujecki and Zaborowski (1968) and next by Nunberg (1986) and . Common species, caught from late spring to autumn in variety of environments. Most, however, it can be found on dry meadows, wastelands and among ruderal vegetation.

Coccidula rufa
Because to the limited number of communities around the waterfronts in the Rogów region, this species of ladybird is quite rare. In summer, rarely collected species, because the whole development goes high in the crowns of well-exposed, old pines. The species collected in the wintering period, in the bark of living trees, especially at their base. Specimens are usually found singly, often in the company of Harmonia quadripunctata (Pont.) and Myrrha octodecimguttata (L.).

CONCLUSIONS
Ladybirds are one of the better-known families of beetles in the Rogów region. There are 56 known species representing approx. 75% of all species in our country. As for this poor, agricultural region with a relatively small mosaic of natural environments, this result seems to be very high. Studies have shown a new species for the Polish fauna. It is Nephus (B) bisignatus. Given the ecological requirements of some species which are not caught yet from the Rogów area, it is possible to catch a few more species. However, these species are extremely rare in other regions of the our country.
