blue orchard bee
July 22, 2009
In the west it’s known as the orchard bee. Last year I read about them and decided to build some nest blocks for them. Here is the results of my efforts. In May they are busy gathering pollin for their young. Now the holes are filled, and the young are pupating.
Thanks for sending us this wonderful documentation of nesting Blue Orchard Bees, Osmia lignaria. According to BugGuide: “It is being managed and developed for use as fruit trees pollinator.“
