Buprestid beetles are one of the important beetles in Kurdistan province of Iran. Different characteristics of their biodiversity were studied by using window, colored pan and colored sticky trap. A total of 222 specimens from 26 species were caught by the traps during appearance of adults. Evaluation of dominance structure of species showed that Buprestid beetles of Kurdistan rangelands include 1 Eudominant species, 1 Dominant species, 4 Subdominant species, 12 rare species and 8 Subrare species when Heydemann classification was used. Investigation of richness fluctuations of species during appearance of adults showed the highest and the lowest considered index in July and October. The highest value of index was obtained in July and June while minimum value was observed in August.
