Notes. Communal nesting in Maine described by Osgood (1989) . Andrena crataegi is one of the most abundant wild bees in apple and cherry orchards in Michigan ( Gibbs et al. 2017 ), but the relatively late flight season of females, better matching the bloom of hawthorne, may reduce its value in some areas ( Gardner & Ascher 2006 ).
