Last summer I discovered that Common Milkweed attracts insects to its flowers during the night, as well as during the day. But they’re different insects. There are more moths at night, as well as ants, craneflies, and ambush bugs. I have several plants of Common Milkweed near the house that bloomed from the end of June to mid-July. Here are photos of the insects I saw there.
It was difficult to get a photo showing how many insects are on the flowers at one time. When I got too close, some of the insects would fly. But these are the ones that show it best.

These are photos of individual insects, or smaller groups of insects. I’ve identified them when I can.
