1056RE: aggregating Megachile and nest site longevities

    Folks- in fact Osmia and Megachile do aggregate on occasions, but typically the ground-nesting species (or any for cavity nesters, if available holes are also aggregated).  Attached is a paper reporting a case of the former. 


    As to longevity of nesting aggregations, the longest yet known is ½ century, with a summary in this other paper of mine on alkali bees (which rounds up both published and validated pers comm. sources).


    In the event that the attachments don’t post, Sam and I will work out a way for you to get them.
