Objective To investigate the composition and distribution of fleas in different natural and geographical environments in Liaoning Province. Methods Using ecology, animal geography and morphological taxonomy principles and methods. Results So far, 47 species of fleas were found in Liaoning Province, belonging to 6 genera and 23 genera, including 6 endemic species in China, 6 species widely distributed in the world and 4 widely distributed species in Liaoning Province. There were 15 species and 15 genera of flea species distributed in the area of Liaodong hilly coniferous and broad-leaved mixed forest. There were 17 species of flea species belonging to 13 genera and 13 species of flea species distributed in the Jiao-Song oak forest area in Liaodong Peninsula. 19 species of 16 genera and flea species distributed in the meadow steppe community of Liaohe Plain.
