It is well known that insect pollinator populations are declining and a lack of nutrients (i.e flowering plants) may be a contributor to this decline. Insect pollinators forage for pollen and nectar, which provides proteins, fats, and carbohydrates, from flowering plants. Current research on pollinator foraging behavior focuses on pollinators that forage on the ground thus overlooking those that forage in trees. Trees such as Kousa dogwood (Cornus kousa) and crabapple (Malus sp.) bloom in early Spring, even before herbaceous perennials and forbs. Thus trees are likely the only places for early flying pollinators to find food. On Providence College campus, I studied bees foraging in trees using traps strung up via a pulley system. I chose 14 tree species that are likely to be pollinator-friendly based on past research and flowering times. Each tree had traps strung up both in the canopy and at the base. Each week contents of traps were collected and bees were pinned and identified to genus and when possible species. Pinned specimens will contribute to the Providence Pollinators reference collection and inform on-campus tree management for pollinator conservation.
