Hi Bob, There is even a North American paper wasp, Polistes major, that's recently been reported as nesting in Spain (2013). (Rasplus et al., 2010, recorded 286 hymenopteran species introduced into Europe; haven't checked which are North American - some of those are deliberate introductions of course.) James M.

Certainly we have hundreds of European introductions here in North America but what about the other way around? I'm hard pressed to think of any?
