The dispersion and phenology of sawflies and aculeate wasps in the Síkfőkút oak forest, Hungary (Hymenoptera)* J. Papp and Zs. Józan The dispersion and phenology of sawflies and aculeate wasps in the Síkfőkút oak forest, Hungary (Hymenoptera) - Sawflies (Symphyta) and aculeate wasps (Aculeata) were taken with Malaise traps in the Síkfőkút oak forest, NE Hungary. The traps were operated in three vegetation layers of the forest: above the canopy (25-27 m), in the canopy (12-14 m), in the shrub + herb layer (0-3 m) and outside the forest in a meadow (0-1 m), and, furthermore, the traps worked in the time-period April-November 1987. Altogether 110 species in 374 specimens were captured (Symphyta 16 species, Aculeata 94 species). All species are enumerated in alphabetic order and in a tabular form (Tables 1-8) with the indications of collecting heights and time data. The aculeate wasps are grouped according to superfamilies (Tables 2-8). Two aculeate species (Dipogon monticolus Wahis, Pemphredon balticus Merisuo) proved to be new to the fauna of Hungary. Regarding their trapping data two sawfly species (Apethymus abdominalis, Athalia rosae) and thirteen aculeate species (Tiphia minuta, Dipogon subintermedius, Vespula germanica, V. vulgaris, Crossocerus quadrimaculatus, Pemphredon lugens, Psenulus fuscipennis, P. pallipes, Trypoxylon attenuatum, T. flgulus, Andrena minutuia, Heriades truncorum, Sphecodes ephippius) were appropriate for a detailed analysis. The dispersion of the Symphyta and Aculeata species shows the following figures (a) regarding their occurrence in a single vegetation layer as above canopy: 1-4 species, in the canopy: 38 species, in the shrub + herb layer: 2-25 species and in the meadow 8-19 species, respectively; (b) regarding their trapping in four vegetation layers: 0-8 species, in three layers: 1-9 species and in two layers: 1 - 22 species, respectively. The phenology of the sawfly species and three aculeate superfamilies (Pompiloidea, Sphecoidea, Apoidea) are figured in coordinates (Figs 1-4). INTRODUCTION This is the second and coincidentally the concluding part of our account on the hymenopterous insects captured with Malaise traps during the vegetation season April November 1987 in the Síkfőkút oak forest, near to the village Noszvaj in NE Hungary. The present survey was carried out within the "Síkfőkút Project" managed by the Kossuth Lajos University at Debrecen. In the first part of our account (Papp 1994) the dispersion and phenology of the braconid wasps were interpreted along with a review of the Turkey oak - sessile oak forest (Quercetum petraeae-cerris) association where four Malaise traps had been set up in four layers of the vegetation, namely, above the canopy (in a height of 25-27 m), in the canopy (12-14 m), in the shrub + herb layer (0-3 m) and in a meadow (0-1 m) about 200 m from the forest. For further details and descriptions, please, confer the first part (Papp Î994: 305-306, 318). * The elaboration of this material was supported by the National Scientific Research Fund (OTKA) No. T331 80.
