Lalep, Thanks to all that replied to my request for info on O-b Sulphurs. I learned that they occur naturally and have also been released by several people in both Baton Rouge and New Orleans over the past few years. They use several varieties of senna and cassia found in urban gardens and a sustaining population seems to be in place. I severe winter would test this population. Another question and I promise the last for a while. This has been a good year for White Peacocks in New Orleans as well. Perhaps I am again unaware of there status relying mainly on field guides. I am wondering if this is another species that local butterfly enthusiasts have raised and released in New Orleans? When visiting my son in Orlando this summer, they were everywhere we went. I was thinking this may have been a really good year for them in their published ranges as well. Thanks, Dave Patton
