Sweat bees

Asked August 2, 2017, 1:31 PM EDT

In the last few days we have swarms of sweat bees. In the garden; on the lawn ; near the pool. I never recall having an infestation of these in past years. Is there an explanation for them?

We have not had reports of anything out of the ordinary about this. It just may be a good year for them.
It is also a good sign because they are beneficial pollinator insects that are ever more important as honeybee populations are declining.
