with in October (Fig. 2). In the case of A. abbreviatus

, there were adults found both in grass and in the canopy of peach-trees approximately in equal numbers, during the whole flight period (Fig. 3). The larvae were detected at the grass-level during the time of sweep-net collections. So far we do not know the herbacous host plant of the larvae. However, the larvae of the three species were successfully reared on celery leaves. As a consequence of the rearing experiments, the specific identity of A. abbreviatus

, A. atomarius and A. mayri larvae and adults could be verified. (Specimens of the adults are deposited in the Zoological Department of the Hungarian Natural History Museum, Budapest.) The larvae of A. abbreviatus, A. atomarius and A. mayri were described according to specimens preserved in alcohol. Fig. 2. Flight period of Allygus atomarius adults, and their distribution at the grass-level and in the canopy of cherry trees During field examinations, the larvae of the three species could be collected first in the last decade of May, while the last larvae were found at the end of June. For describing and identifying the larvae the pattern of the dorsal surface proved to be useful. Differences between males and females of a species, during larval stages, are insignificant. Still, the most important deviations appear in the shape and sculptural patterns of the developing ovipositor and the genital segments (Fig. 4: A-B). It is interesting to note
