Biology

Adults are on wing from June to August in one generation in the northern part of the range. There are two generations with adults on wing from May to August in the south. Adults feed on the nectar of various flowers, including Lonicera japonica, Petunia × atkinsiana, Philadelphus coronarius, and Phlox species. It is one of three main pollinators of the rare orchid Platanthera praeclara.[3]

They are known to feed on Parthenocissus quinquefolia and Ampelopsis species. They are often found on wild and cultivated Vitaceae, including grapes, and they can sometimes be found in vineyards feeding on the leaves.[3]
