Here's a list of extinct and presumably extinct (or missing in action - not seen
for decades) butterfly taxa from the US that was pulled down from the Bioserve
website (took about 3 minutes to conduct the search). I simply searched species
and subspecies known to be extinct (GX or TX) and those thought to be extinct (GH
and TH). Here's what the US heritage programs think:
<http://www.natureserve.org/aboutd.htm> If you go to this link, you can probably
search each species individually to see what the contributing factors were.
