This solo bee could help orchards outlast the honeybee crisis

Pollinators
If you grow fruit trees, the small blue-black bees nesting in hollow stems near your yard each spring may be doing more pollination work per visit than any honeybee you'd hire.
Most bees don't live in hives with a queen, they live alone, and one of these solitary bees, the Blue Orchard Bee, is really good at pollinating fruit trees like apples and cherries. Scientists reviewed everything known about how it nests, forages, and survives, and found that farmers and gardeners could rely on it more if we understood its habits better. The catch is that researchers still have big gaps in knowledge about what stresses this bee out and how to help it thrive.
Key Findings
About 80% of all bee species are solitary, not social like honeybees, making them a more representative model for conservation research
Osmia lignaria (Blue Orchard Bee) is increasingly used as a commercial pollinator for orchard crops across North America
The review identifies major gaps in knowledge around the bee's developmental plasticity, nesting behavior, and response to environmental stressors
chevron_right Technical Summary
A gentle solitary bee called the Blue Orchard Bee is emerging as a key backup pollinator for orchards as honeybee colonies struggle, and scientists say we still don't know enough about its needs to manage it well.

An apple is the round, edible fruit of an apple tree. Fruit trees of the orchard or domestic apple, the most widely grown in the genus, are cultivated worldwide. The tree originated in Central Asia, where its wild ancestor, Malus sieversii, is still found. Apples have been grown for thousands of ...
