| Summary: | The study of floral phenology patterns and floral visitors of palms is key to understanding evolutionary interactions between plants and insects. We studied the flowering pattern and floral visitors of Wettinia kalbreyeri in an Andean montane forest of Colombia. We monitored 100 adult palms throughout 1-year and observed an asynchronous flowering pattern at the population level. Collectively, those 100 individuals developed 125 inflorescences, composed of 96 staminates, 28 pistillates, and 1 androgynous. We classified 39 morphotypes of insect floral visitors, including beetles, bees, and flies. The composition and abundance of floral visitors between staminate and pistillate inflorescences were markedly different. Sap beetles – Mystrops – were the most abundant visitors in both pistillate and staminate inflorescences. We suggest that the higher production of staminate inflorescences compared to pistillate inflorescences and the availability of inflorescences throughout the year may promote a permanent and abundant community of floral visitors. This study suggests that Mystrops are associated with Wettinia species in high altitude forests, as it also occurs in Ceroxylum species.
