British moths in North America

[Dr Mark Young, Culterty Field Station]

Dear All,

Please may I ask for some help from those of 
you in North America.  I have a colleague who 
is beginning a study of Lepidoptera which 
have "invaded" new areas.  Since 1900 we have 
had 30 or 40 invaders in Britain and yet only 
2-3 of these come from USA or Canada, which 
may make sense in terms of the distance 
involved, but does not make sense if 
significantly more British species have made 
the leap across to the USA.  The question is, 
can anyone tell me which British species have 
become established in North America, or point 
me to a reference that lists them?

We know of the pest species, such as 
Operophtera brumata or Lymantria dispar, but 
are there many others?  Any help would be 
gratefully received.

Many thanks,

Mark Young
