The Cosmos Cupcake White blossoms are a great attraction for bees.
Not only are these very lovely blossoms, but they also provide nectar and pollen, as well as a safe place to sleep.
Here are two Summer Longhorn male bees settled down for the night.
As long as the blossom is in bloom they seem to return every evening and leave late the next morning when the temperature is just right. It's like an motel for them.
Here is a sweat bee, most likely a Lasioglossum kincaidii in another Cosmos Cupcake White, gathering pollen and sipping nectar.
The spots on the petals are little insects, but I'm not sure what kind they are.
