I have 4 false heather in my yard and I was out today surveying the garden and noticed that there were lots of little flying insects going in and out of each flower like bees would do. The insects looked just like small flies, are there any bees that small that look like flies. I sure hope that these plants don't attract that many flies or I will not be planting them next year. If anyone could shed some light on this I would greatly appreciate it.
