Hello All,
I raise Osmia lignaria (Blue orchard bee or the orchard mason bee) and would
be glad to answer specific questions.  Please search the University of Idaho
site for the basics and I will help with specific questions.

 Does anyone have experience of mason bees (Osmia spp)? I'm aware that trap
 nests are commercially available, and that they can be used for
 pollination. I'm interested in using them at an urban site in the UK, and
 I'd be grateful for any pointers.
