I was noticing some new dandelion blooms and was pleased to see that my bees had found about every one, then I looked closer, and they wern't bees, these things have been in the house all winter, and we can't figure out how to get rid of them, when I saw them on the flower, I thought, I hope pollen doesn't attract them to the hive. Anyone know what they are, or if they will bother the bees?
