Let's not forget the monarch butterfly although a great disperser/migrator, European monarchs were probably limited to the occasional adult visitor until the importation of exotic milkweeds (Asclepias, Gomphocarpus) as ornamentals that let them establish breeding populations in Spain.  Does that count as an "introduction"?  Or maybe a colonization?

Hi Bob:

At least one N. American leaf miner (Gracillariidae: Macrosaccus robiniella (Clemens)) has been introduced into Europe on the likewise introduced Robinia pseudoacacia L.  See attached report.

Hi Rob,

There are also non-social wasps that have been introduced to Europe. One example is the sphecid Isodontia mexicana, which is native to much of North America (including parts of Canada). It now occurs in several European countries as far north as Germany.

Cheers, Matthias

Can anyone think of North American insects introduced into Europe.  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?  Bob
