Abstract In order to make a scientific and practical plan for conservation of an endangered species, it is indis-
pensable to identify the kind of insects effective in legitimate pollination and to clarify the main factors on their
pollination behavior. Primula merrilliana, a small biennial rosette herb with distylous flowers, is an endangered
and endemic species of China. In this study, the effective pollinators and the effects of flower density and popula-
tion size on pollination efficiency were investigated. The results indicated that the primary effective pollinators of
this distylous herb were two bee flies, Bombylius major and Anastoechus chinensis rather than Thrips sp., which
was previously considered as an effective pollinator for the plant
