Results In course of the years 1996-1997 the total of 4277 neuropteroids were collected in the Dráva region. The material was determined in the family Coniopterygidae based on the internal and external genitalia characteristics, with other families mostly on external morphological features, including the sexual organs. In this way 56 species were determined in the collections. Together with earlier collections this meant 66 species and this number was further augmented by six species, indicating an extraordinary diversity of the Neuropteroidea fauna along the Dráva river. New populations of following species were established: Phaeostigma notata, Phaeostigma major, Helococonis lutea, Osmylus fulvicephalus, Hemerobius marginatus, Sympherobius fuscescens. From faunistical point of view the following species have to be emphasised. Phaeostigma major (Burmeister, 1839). The species is an expansive pontomediterranean element in the Hungarian fauna; it has been found in Hungary - with the exception of the Great Hungarian Plain - on southern slopes, hillsides and ranges of medium height (Fig. 1.). In those habitat it lives in thermophilous oak forests, karst scrub-forest but it has been found in planted orchards as well. According to ASPÖCK et al. (1991) it is an euryoecic species that is, howewer, not common. Based on many years' collection of Raphidioptera its populations seem to be rather limited in Hungary, so we have very few data on its distribution. The data found in collections or in the literature refer only to single individuals. This would be enough reason to wish that all Raphidioptera should be protected by law. Osmylus fulvicephalus (Scopoli, 1763). Expansive holomediterranean element. Its development is bound to the presence of water. From its three larval instars the second or the third is overwintering (ASPÖCK et al. 1980). Its pupal instar takes about two weeks. Its distribution in Hungary is shown in Fig. 2. Osmylus fulvicephalus is a species of ranges of medium height and hilly country. It is not present on the Great Hungarian Plain, the Little Hungarian Plain (NW Hungary) and Inner Somogy that was intensively studied. It occurs in hilly areas, like in Vas, Zala and Zselic. Based on the collections it can be established that its characteristic habitats are the surroundings of limnocrenous springs and
