Mason Bees are early spring pollinators that emerge when temperatures are 50° F (10° C) or warmer over three to four consecutive days.
Mason Bees are valuable pollinators of fruit and nut trees, some berries, and a few early spring flowers. They also like maple trees. A single Mason Bee will visit between 1,600 to 2,400 blossoms daily, and pollinate over 90% of them. A female visits an average of 75 flowers per foraging trip.
