On my country road walks in the evenings, I have been seeing these little insects nestled together in the black-eyed Susans. They are male long-horned bees. The males have unusually long antenna or “horns” compared to the females, and they sometimes cluster together inside flowers while they sleep. They are invaluable pollinators of many crops and plants.
