male long-horn bees

I have planted both front and back yards with plants to attract and support native bees, and presently have upwards of 30 species foraging among the colorful blooms. Build it and they will come. Male long-horn bees habitually sleep in groups, either inside a flower or holding onto a stem with their jaws. They begin looking for suitable nap sites by late afternoon or early evening. Boys night out, so to speak.
