Trophic relationships between nestbuilding megachilid bees and flowering plants in Kuznetsk-Salair region are investigated. Host plant’s diversity includes 21 families, 58 genuses and 80 species of plants. The most host plant’s species are Fabaceae, Asteraceae and Rosaceae. The most species of Megachilidae are associated with these families of plants. Megachile ligniseca and M. willughbiella are characterized by the widest spectrum of trophic relationships. M. ligniseca is associated with 7 families, 17 genera and 18 species of plants; M. willughbiella is associated with 6 families, 10 genera and 11 species. Megachilid bees are divided into 4 groups depending on the character of the trophic relationships (widely and strictly polylectic, widely and strictly oligolectic). Widely polylectic group characterized by the most number of species (18 species, 52,9%) and numerical abundance (61,3% of total).
