and Clytrinae with 11 species out of 4 genera, the Criocerinae with 4 species out of 2 genera, respectively the Donaciinae, Zeugophorinae, Lamprosomatinae with one species each. The best represented subfamilies are the Halticinae with 104 species out of 17 genera, the Chrysomelinae with 52 species out of 15 genera while less represented are the Donaciinae, the Zeugophorinae and the Lamprosomatinae subfamilies.

As indicated in Table 1 the majority of species fall within the category of herbaceous, phytophagous grassland as it is the case of the representative subfamilies, like the Halticinae with 90.38%, respectively the Galerucinae with 81.81% and the Chysomelinae with 65.38%. Depending on the number of host plants, on the nutritive spectrum the species fall into the monophagous, oligophagous, polyphagous categories. In case of the species from the Chrysomelidae family, I have processed the data on host plants relying on the existing literature [1,2,3,4,7,8,9,10,11]. After processing the data from the researched habitats it resulted that out of the total 227 species the predominant ones are the oligophagous with 124 species, followed by the polyphagous ones with 79 species while the fewest in number are the monophagous species with 24 species (Fig. 1).

Within each nutritive category the subfamilies are distributed through differentiation. Thus, within the monophagous species the best represented are the Halticinae subfamily with its 12 species, followed by the Chrysomelinae subfamily with 6 species, the Cryptocephalinae subfamily with 3 species, the Galerucinae with 2 species and the Lamprosomatinae with one species (Fig. 2).
