Abstract：This study takes Prunus lannesiana of different colors from peak flowering to fading period as study ob-ject,followed by a study on the composition of follower-visiting insects and their visiting behaviors.A total of 749 insects belonging to 7 orders and 41 families were captured.The dominant community was Coleoptera and Hemip-tera,with 303 and 186 individuals,accounting for 40.45%and 24.83%of the captured insects,respectively.The flow-er visiting behavior was mainly for flower feeding.The commnity and behavior diversity of visiting insects vary greatly from different flower colors of Prunus lannesiana.The diversity index of Prunus lannesiana of different col-ors from high to low was light pink＞green＞light green＞pink.The order of evenness index was light pink＞green＞light green＞pink.The order of dominance index was pink＞light pink＞light green＞green;and the or-der of richness index was light pink＞green＞pink＞light green.The diversity,evenness and richness index of the light pink cultivar were higher than those of other cultivars,while the dominance was lower,indicating that the spe-cies of flower-visiting insects of this cultivar were abundant and the community was stable.
