The Palouse prairie is a severely fragmented system located in southeastern Washington and northern Idaho. Most of the historic range of the prairie has been converted into agriculture, and little of this plant community remains, mostly in small patches that were unable to be converted into agriculture. As a result, this diverse plant community is imperiled. Previous studies have characterized the arthropod communities of these prairie remnants, primarily using non-specific trapping techniques. We linked insect visitors with specific flowering plants to investigate species-specific plant-insect associations and community structure. We examined seven plots of high-quality remnant Palouse prairie throughout the entire course of two flowering seasons. For each plant species, we used direct netting techniques to capture insect visitors on the inflorescences, ensuring that each insect captured could be associated with a specific plant. We sampled each plant species for one hour per species per plot multiple times throughout its blooming period. These insects were identified to the lowest taxonomic level feasible. We sampled thirty-six plant species and captured a diverse range of insects; primarily Hymenoptera, but also Diptera, Coleoptera and Lepidoptera. We focused on known groups of pollinators to visualize a pollinator network to identify key supporting plant and insect species and to investigate pollinator network composition throughout the flowering season.
