[Pollinator] Bee Houses

[Droege, Sam]

In the Washington D.C. area all or nearly all the spring "blue-orchard bee"
sized holes are filled with just *O. cornifrons *and *O. taurus* (both
Asian species) in the spring.  *Osmia lignaria *is quite uncommon as a
species.  Smaller diameter holes and larger holes later in the season seem
to get a greater diversity of nesting species of bees and wasps, but I
haven't made and exacting study of it.
