Untersuchungen über die Chrysopiden des Bezirkes Scheibbs (Niederösterreich). Beitrag zur Kenntnis der Ökologie, Phänologie und Verbreitung der Chrysopiden Mitteleuropas (Neuroptera: Planipennia).

Abstract

During a period of about ten years 4048 specimes of the neuropterous family Chrysopidae were collected in the region of Scheibbs (Lower Austria). The material comprises 17 species, namely Nothochrysa fulviceps, N. capitata, Hypochrysa nobilis, Chrysopa perla, C. dorsalis, C. septempunctata, C. phyllochroma, Anisochrysa flavifrons, A. ventralis, A. prasina, A. carnea, A. albolineata, Tjederina gracilis, Nineta flava, N. vittata, N. pallida and Chrysotropia ciliata. On the basis of ecological results Anisochrysa ventralis and Anisochrysa prasina appear to be two clearly distinct forms thus confirming the assumption of other authors that they represent to valis species. The results of collections are shown in tables and diagrams. The ecology and seasonal dispersion as well as the vertical and horizontal distribution of each species are discussed in detail.
