<p>Pollination is a vital ecosystem service underpinning the production of both global food crops and wild plants. Although coffee (<i>Coffea arabica</i>) is capable of self-pollination, animal-mediated pollination is essential for maximizing yield and maintaining cup quality. This study investigated insect flower visitors of cultivated <i>C. arabica</i> and the endangered wild species <i>Coffea fadenii</i> in the Taita Hills, Kenya. Specifically, we compared species richness, diversity, abundance, and community overlap of flower visitors between the two coffee species to inform management and conservation strategies. Coloured pan traps and limited time searches were employed to sample for insect flower visitors. A total of 2,931 individual insect visitors, representing 153 species across four insect orders (Hymenoptera, Coleoptera, Diptera and Lepidoptera), were recorded on both species. Species richness and diversity were greater in <i>C. arabica</i> than <i>C. fadenii</i>, though overall visitor abundance did not differ. The dominant visitor on <i>C. fadenii</i> was <i>Melyridae sp</i>. 1, a soft-winged flower beetle (37.12%), whereas <i>C. arabica</i> was primarily visited by <i>Apis mellifera</i> (19.31%) and <i>Rhyncomya soyauxi</i> (11.50%). Non-metric multi-dimensional scaling (NMDS) ordination of flower visitor communities found significant differences between the two species, suggesting limited potential for pollen exchange. These findings highlight the distinct partitioning of pollinator assemblages between cultivated and wild coffee, emphasizing the ecological importance of insect pollinators for both the in-situ conservation of <i>C. fadenii</i> and the enhancement of <i>C. arabica</i> yields. Moreover, the prominent roles of beetles and flies alongside bees suggest that maintaining taxonomic diversity of flower visitors may be crucial for functional redundancy and effective pollination.</p>
