Tetraopes tetrophthalus on Common Milkweed - Tetraopes tetrophthalmus
Nashua, Hillsborough County, New Hampshire, USA July 8, 2022
Found at dusk on a leaf of Asclepias syriaca. The plant is against a porch that had the porch light on. I have several other patches of Common Milkweed that aren't near artificial light. They seem to attract fewer beetles.
