lakes, and wells. They can be found near the surface of aquatic ecosystems, but also at considerable depths on the muddy bottoms of lakes and wells (M e l l a n b y, 1968). Certain species can live buried several centimeters in mud. Their dissemination is of a local nature. For most of their life cycle, the larvae are immobile, i.e., they rest in the water and obtain oxygen from it (M a c a n, 1960). The long cylindrical body (Fig. 1) is transparent or semi-transparent and of a white or yellowish color; the only easily distinguishible features are the black eyes on the

Larvae of the family Chaoboridae live in small clean bogs, lakes, and wells
During 2005, hydrobiological investigations were carried out once a month on a small stream (Šugavac) and in two wells on the “Radmilovac” Experiment Ground of Belgrade University’s Faculty of Agriculture near the city of Belgrade
Following identification and thorough checking of previously published data, it was established that these findings at the indicated localities on the “Radmilovac” Experiment Ground are the first for the entomofauna of Serbia
Summary
Larvae of the family Chaoboridae live in small clean bogs, lakes, and wells. They can be found near the surface of aquatic ecosystems, and at considerable depths on the muddy bottoms of lakes and wells (Mellanby, 1968). Head and two pairs of air-filled hydrostatic organs (air sacs or bladders), one on each side of the body (ab, Fig. 1). One pair of air bags is in the thorax and the other on the seventh abdominal segment (Roskošny, 1980).
