By all means, plant lots of flowers for pollinators.
There are over 20,000 known bee species in the world, and 4,000 of them are native to the United States. They range from the tiny (2 mm) and solitary Perdita minima, known as the world’s smallest bee, to kumquat-sized species of carpenter bees. Our bees come in as many sizes, shapes, and colors as the flowers they pollinate. There is still much that we don't know about native bees—many are smaller than a grain of rice and about 10% of bees in the United States have yet to be named or described—but all of these bees have jobs as pollinators.

Maybe those are not drones?
Why lots of flowers?
There are about 350,000 pollinator species in the world. While bees might be the most well-known, other insects, including butterflies, flies, moths, beetles, and wasps, also pollinate. Birds, bats, other small mammals, and lizards can act as pollinators, as well.

It is great that you have lots of bees in your backyard.
