Abstract Insect pollinators are essential for natural ecosystems. Without pollination, native plants are less likely to be able to persist. As natural ecosystems have become more fragmented and degraded, interest in their restoration and preservation has increased. Understanding the roles that individual plant and pollinator species play in an ecosystem can assist with these tasks. One way to examine the ecological drivers for patterns of pollination is through module analysis. The Palouse Prairie is a fragmented native prairie that supports high plant and insect diversity and has experienced severe habitat loss. Bees were collected on native plants in prairie fragments in 2022 and 2023 to construct a plant–pollinator network. From this network, modules were computed and analyzed. This network contained 10 modules representing multiple different ecological patterns, including modules grouped by morphological, taxonomic, and phenological similarities. These modules also identified plant–pollinator pairs with specialized relationships. The network was then analyzed to identify plant and insect members that play structural roles in the network. Understanding the patterns of interactions represented in the modules and the network structure may allow for better conservation and restoration of this imperiled ecosystem.
