Sažetak
During the period from April – September 2004., the first systematic investigations of dragonflies of the upper Drava were carried out at 10 locations. The following methods were used: the method of collecting by entomological nets, the method of strolling and observing and the method of taking photographs. Mapping and digital analyses of the data were done by GIS tehnology, and the ArcView 3, 0 program was used. The similarities of fauna were established according to the method of SØRENSEN (1948). On the basis of the 924 collected individuals at different stages of life (larvae - exuvia and adult individuals), a total of 43 species, 22 genuses, 8 families i 2 suborders of the order Odonata were established. The greatest abundance in qualitative structure (frequency of encounter) was found in the species: Calopteryx splendens, Platycnemis pennipes, Coenagrion puella, Ischnura elegans, Anaciaeschna isosceles and the smallest in the species: Chalcolestes viridis, Coenagrion ornatum, Brachytron pratense and Gomphus flavipes. The established qualitative structure of the dragonflies of the Drava river area represents 59, 72 % of the total number of species in Croatia which proves that the investigated area is significant for the protection of the biodiversity of the dragonfly fauna.
