My regret is that the article didn't identify the species concerned ... otherwise, I would have had
lots of fun tracking them down!
The problem is that there's an entire Genus of butterflies, namely
Diaethria, whose members have "80" or "88" wing patterns, of which
Diaethria anna is but one of about a dozen such species ...
Diaethria anna can be viewed
here.
If you go to
this huge list of butterflies found in the Americas, you can search through the Genus
Diaethria and see a
huge number of photos of the butterflies in question. For example,
this page covers
Diaethria astala.
