The Sugar palms are an important commodity with a pollination process that is highly dependent on insect activity. However, information on the diversity of pollinator insects and visitors to these plants, especially at various altitudes, remains limited. This study aims to determine the diversity of insect pollinators and visitors, as well as their relationship with environmental factors, in sugar palm in Lintau Buo Utara District, Sumatra Barat Province. Observations were made at three altitudes (500–700 meters above sea level, 700–1000 meters above sea level, and 1000 meters above sea level) using purposive sampling, visual control, and Pearson correlation analysis. The study's results revealed a total of 862 insect individuals, comprising 712 Insect pollinators and 150 visiting insects. The primary Insect pollinators are from the genera Apis, Vespa, Episyrphus, and Polyrhachis, while Insect visitors include Aphrophora, Macroglossum, Spodoptera, Anopheles, Anomala, Tipula, Actia, and Blaps. The diversity of insect species was moderate, with a value of 2.04. In contrast, the diversity of pollinating and Insect visitors was 1.42 and 0.62, respectively. The most optimal pollination activity occurs at altitudes of 700–1000 meters above sea level. The Pearson analysis revealed that rainfall and humidity had the most significant influence on the presence of insects, with a strong negative correlation, while temperature had a lesser influence. There is a perfect positive relationship between the presence of Insect pollinators and visitors.
