Fig. 4. Phenology of the apoid species females, 1 Ç in the canopy and 4 in the shrub + herb layer during the time period 9 May - 19 July; 1 Ç each in both layers in May and 3 ÇÇ in July only in the shrub + herb layer and capture days succeeded almost one after the other as 15, 16 and 19 July (see Table 8, too). Sphecodes ephippius is the single bee species (from among the 22) which has been trapped in all four vegetation layers of the oak forest. Out of the seven specimens (1 ? + 7 dd ) 1 Ç + 3 dd were captured in the oak forest and 3 dd in the meadow, i.e. half to almost half in the closed and open vegetations, forest and meadow, respectively. Two specimens (1 *j? + 1 d) fell into trap in May and 5 dd in July (see Table 8, too). A hypereuryoecicous species (Józan 1991: 608). In Hungary it is a nest parasitoid of Halictus bicolor and Andrena ovatula (M. Móczár 1967: 91). REFERENCES* Bajári, E.(1957): Kaparódarázs alkatúak I.
