There are all kinds of bees. We need them to pollinate our flowers. If we didn't have pollinating insects we would have almost no foods left to eat, since foods grow from seeds that grow into plants that bloom and thats' where the bees come in. Seeds for next year's crop can't be made if bees don't do their job of taking pollen from flower to flower. They do this while they get the sweet nectar.
Honey bees make ... you guessed it, honey.
In this area (Kootenays, B.C.) we have a number of honey bees, bumble bees and also the native mason bees.
Mason bees don't make honey for people. but they are great pollinators.
I have put my mason bees' nest box up for the season. Any place that has hollows, like old tree trunks, are places where mason bees may build their nests. We have to make sure we don't disrupt the bees while they work.
