Abstract: The feeding preference and mating behaviors of Epicauta sibirica(Pallas, 1773)were analyzed by observation indoors and in the field. Results showed: 1)Glycine max and Solanum tuberosum were the most preferred host plants for adult; 2)Mating behavior of E. sibirica included both courtship and copulation. The courtship behavior is repeated several times in one mating process. Courtship behavior lasted(9.60±1.78)min; the interval between the two behaviors lasted(6.55±1.92)min. The species assumes linear position in the copulation. The copulation behavior occurred at 8:00 to 13:00 mostly and lasted(165.44±14.17)min.

Key words: Epicauta sibirica, adult, feeding preference, courtship, copulation
