An exploratory survey of flower-visiting insect records and floral associations from three agricultural case sites in Central Java, Indonesia. Biodiversitas 27 (6): d270629. https://doi.org/10.13057/biodiv/d270629. Flower-visiting insects contribute to agroecosystem functioning, yet the composition of local visitor assemblages and their floral associations remains incompletely documented in many tropical smallholder landscapes. We surveyed one home garden, one corn field, and one citrus orchard in Central Java, Indonesia, as three exploratory case sites. Direct roaming observations were made for six days in June 2024 during morning and afternoon sessions. Only insects that contacted anthers or stigmas were counted, so the records indicate potential pollinators rather than confirmed pollination events. The survey produced 167 records representing 3 orders, 8 families, and 32 species. Lepidoptera dominated the observations with 148 records (88.62%), compared with 14 Hymenoptera and 5 Diptera. The home garden yielded 70 records and the highest Shannon diversity (H′: 2.56). Species richness was 15 in both the home garden and corn field and 11 in the citrus orchard; evenness ranged from 0.88 to 0.95, while Simpson dominance ranged from 0.09 to 0.14. Jaccard similarity between pairs of sites was low (0.13-0.20), showing marked turnover in the recorded assemblages. The floral-association summary contained 16 flowering plant species from 11 families. These results describe a short seasonal snapshot rather than a general effect of agricultural setting because each setting was represented by one site, observations covered only six days in one month, and floral abundance and plant-level observation effort were not standardized. Even with these constraints, the dataset provides a baseline for selecting sites, taxa, and floral resources for future work. Replicated surveys across seasons, with standardized effort and direct measures of pollination effectiveness, are needed to determine whether the patterns observed here extend beyond these three case sites.]]>
