FORMICOIDEA All twelve ant species taken in Síkfőkút are frequent to common all over Europe and in Hungary too, the majority of them are true inhabitants of the oak (and other) forests. Here they are living in an extremely high number nesting in soil cavities, under stones, in mouldy tree trunks etc. Peculiarly enough, this huge quantity is not registered by the Malaise trap samples. Every species was trapped in one to four specimens. This unanalizable trapping result may again conclude to the unambiguous experience that Malaise trap is unsuitable to render real figures to explain dispersion, phenology etc. of the ants. SPHECOIDEA The digger or sphecid wasps have been trapped in the highest species as well as in the highest specimen number in Síkfőkút, i.e. 30 and 143, respectively. Though the species number, 30, is low (in Hungary 276 sphecid species are recorded; Józan 1993), from among them one species, Pemphredon balticus Merisuo, 1972, proved to be new to the fauna of Hungary. Since its description the species was reported from several European countries everywhere sporadically (Lomholdt 1975: 97). Fig. 3. Phenology of the sphecoid species
