She Sealed the Door, Then Lay Down to Die
In late April, in a hollow stem behind your shed, a small metallic-blue bee is finishing the last act of her life. She has spent six weeks alone, building a single column of mud chambers, each one stocked with pollen, each one holding one egg.
Now she walls up the entrance with mud. She will not see her children hatch. She will be dead within days.
We swat her at the porch light. We seal up "wasp holes" in the eaves. We assume any bee that doesn't live in a hive is somehow wrong.
In reality, the native Blue Orchard Mason Bee (Osmia lignaria, Status: Secure but in regional decline) is one of the most efficient pollinators in North America. A single female pollinates as many apple flowers as 100 honeybees. She is solitary, she is stingless in practice, and she will be entirely dead before her own offspring chew their way out of the mud next spring.
Leave the hollow stems standing through winter. Drill no-pesticide nest blocks. Her motherhood is a single sealed door — and we keep painting over it.
