Mason Bee

Osmia spp


blue bee


near flowers


Mason bees live by themselves in holes and hollow stems. A female mason bee lines her nest with mud. She gathers nectar and pollen from flowers. She puts a pollen ball in the hole. She lays an egg on the ball. Then, she makes a wall of mud. She does it many times in her nest. Then, she seals it up with mud. The baby bees grow up in there nest. The adult bees chew through the mud and leave the nest. They start their own families.
