Out of the thirty species twenty-four were trapped in a low number of specimens ( 1 to 4-5), these species are only recorded and are unsuitable for further evaluation. The remaining six species with their more or less sufficient quantity are suitable for further analysis (see Table 7, too). Crossocerus quadrimaculatus prefers to construct its labyrinth-like nest in open sandy slopes or the like, this ecological requirement does not restrict the species to wooded environment. However, the species preys on wingless aphids (Lomholdt 1976: 378) as well as flies, moths and caddisflies (Oehlke 1970: 787) supplying its brood. This Table 7.
