Mason Bees

Osmia

Mason bees are tiny, friendly insects that help flowers grow by spreading pollen. They are great builders and make their homes in small holes using mud and plant materials.

Habitat: Gardens

Appearance

The Mason Bee has a stocky, often metallic blue, green, or black body covered in dense, fuzzy hairs. They are smaller than bumblebees but larger than many sweat bees, with a distinct, often iridescent sheen that sets them apart from the more common yellow and black striped bees.
