Monarch

A Monarch, not a Viceroy. A Viceroy would look like this

Thanks Karen and John.

The south american species is Danaus plexipus erippus. There doesn't seem to be a wiki page for this species but there are some images on this link http://www.google.com/imgres?imgurl=http...

Monarchs are migratory! They go south for our winter, so your spotting is around the right time. There is a mimic called the Viceroy (Family Nymphalidae), but I am 99% positive that Karen is correct.

I thought it was, but everything I have read about monarchs do not show they can be found in Brazil.
