The evolution could occur at the agreed upon in plants and their pollinators. Therefore, the structure of the inflorescence and flowers, often tailored to a specific pollinator species. The structure of flowers usually is constant for species of plants, but it varies in <i>Astilbe chinensis</i>. This may be due to the preferences of their pollinators. However, pollinators have not been the study in <i>A. chinensis</i> hitherto. The present study showed that <i>A. chinensis</i> has a wide range of a visitor, who have different preferences over time visiting flowers, different goals and behaviors. <i>Coleoptera</i> and <i>Hymenoptera</i> dominated among the pollinators of <i>A. chinensis</i>. Environmental conditions have a significant impact on the mode of pollinators visiting the flowers. Temperature and the humidity are important for pollinating of <i>A. chinensis</i>. Temperature and humidity limit the frequency visits of <i>Coleoptera</i> more than <i>Himenoptera</i>, they prefer higher temperatures and lower humidity for visits into flowers of <i>A. chinensis</i>. <i>Coleoptera</i> were not specifies as pollinators <i>Astilbe</i> earlier. Research results are cause for revision characteristics of plants, which is pollinating by beetles. <i>A. chinensis</i> produces small flowers with varying structure, collected in thyrsus, forming a significant amount of pollen over a long flowering period. Therefore, a plurality of pollen must be critical after pollination beetles and flower size, apparently irrelevant.
