The Palouse prairie is a severely fragmented system located in southeastern Washington and northern Idaho. Less than 1% of the prairie remains, mostly in small patches that were not able to be converted to agriculture. 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. We examined seven plots of remnant Palouse prairie throughout the course of the flowering season, late March until early September. For each plant species, we used direct netting techniques to capture insect visitors directly 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. 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 and compared community structure among plant species. We found that many of the plant species sampled had insect communities that were distinctly different even within plant genera and plant families.
