Panicle Hydrangea data on flower visiting insects

Partial Abstract: As available wild habitat for pollinators shrinks, urban and suburban plantings have become increasingly important for maintaining pollinators on the landscape. Hydrangeas are some of the most popular ornamental shrubs in the United States, and panicle hydrangeas in particular have seen a recent surge in popularity. The University of Wisconsin – Madison Arboretum has one of the largest panicle hydrangea collections in the country. We assessed flower-visiting insect assemblages across 46 cultivars of panicle hydrangeas (H. paniculata) and 16 cultivars of smooth hydrangeas (H. arborescens). We collected three years of photo (N = 13,017), visual (N = 776), and physical (N = 1,156) samples of insects. This data is currently being submitted for publication. We will open records to the public after it is published. This dataset includes: Excel files of data, photo vouchers of insects. Funding was made possible due to the Stanley Smith Horticultural Trust.
