Regal Fritillary

[NewtChris]

Well, to be honest, I'm delighted by the debate I initiated on this discussion
group.

But... one possible hypothesis I haven't seen debated in this forum is that of
exotic parasites.   There seems to be plenty of "old growth pasture land"; aka.
prarie land in the extreme north east of the US and of the country side of
Southern Cananda.  

It seems to me the the interruption has something to do with the complicated
overwintering stage of the life cycle of this Lepidoptera or from a foriegn
influence.

Cheers with your efforst....

Chris
