Cailiphora uralensis VILL. Only 10 exemplars were caught in traps, not enough to compile its abundance curve. The specimens of this species in the collection of the Hungarian Natural History Museum are unsuited for a quantitative avaluation, and give but a hint to their seasonal distribution. Their data are : V VI VII VIII IX 1212121212 3 3 2 122 5 1 78 43 8 1 It seems that its flying time may be different from that of the former species and may have a summer maximum. It lives in cities and villages. New for the Hungarian fauna. Lucilia caesar L. The abundance graph (Fig. 3) indicates at least five generations per year, with a maximum in the first half of July. It prefers forests, but occurs in numbers also in cities. Lucilia sericata MEIG. The most abundant and probably the most dangerous synanthropic fly of Budapest and the cities. Producing many generations, it is most numerous in the first half of May (Fig. 4). The explanation may be the fact that a part of the summer generation goes into diapausa and hatches the next spring, together with the autumn generation (MIHÁLYI 1965).
