Abstract

Neuropteroidea communities were studied near Budapest (Nagykovácsi) in an abandoned, mixed orchard and its neighbouring environment: a shrub community without a closed canopy; a shrub level of the canopied oak forest by using Malaise traps. In the open shrub verge of the orchard larger, and in the oak forest more diverse Neuropteroidea community developed than in the other investigated habitats. The Neuropteroidea communities studied did not show stable compositions in the investigated habitats and years. By studying the linkage conditions of different species to different habitats, it was established that Hypochrysa elegans was strongly bound to the shrub level of the closed oak forest. Besides that, both in the shrub level and in the open forest edge, the species Micromus lanosus, Micromus angulatus, Hemerobius micans, Hemerobius lutescens and Hemerobius humulinus were found with higher density. The species Dichrostigma flavipes, Chrysopa formosa, Chrysopa perla, Xanthostigma xanthostigma, Chrysoperla carnea and Dichochrysa prasina occurred in all three habitats, thus they have to be regarded as habitat generalists. By passing beyond these tendencies Dichrostigma flavipes, Chrysopa formosa and Chrysopa perla seemed to be more attached to the shrubby edge.
