Mason Bee (specifically likely a Blue Orchard Mason Bee)

Orchards, gardens, and edges of forests across North America; they utilize pre-existing holes in wood or hollow stems for nesting.

Adults feed on nectar; larvae consume a provision of pollen and nectar gathered by the mother.

Solitary nesters that do not live in colonies. They are active in early spring, creating individual mud-walled cells inside cavities to lay eggs. They are known as 'buzz pollinators'.

Extremely beneficial as highly efficient pollinators for fruit trees and flowers. They are very docile and rarely sting humans unless squeezed or handled roughly; their sting is much milder than a honeybee's.
