Originally posted by OrchidJulie Because this conservatory is in south Florida, the USDA is unbelievably strict about the way it's managed -- multiple airlock doors in and out, not one larval "food" plant inside (plenty of nectar plants and supplemental feeding spots for the adults), etc. so the butterflies cannot escape/reproduce. The garden has an outdoor butterfly garden for native species, the conservatory has only tropical exotics.
The only "complaint" I have about it is that on many occasions, it's been very crowded, often with noisy, rowdy children running about, keeping the butterflies in constant flight. Tough to get one posing for a few shots!
I think those precautions are pretty standard. They even have them here in Canada where tropical butterflies wouldn't survive for long if they escaped from a butterfly house, and where there are few ( if any ) suitable larval food plants in any case. In Florida, those precautions are understandable. Foreign butterflies can establish themselves here in NA. The Cabbage White was brought by European settlers, possibly several times. The European Skipper is thought to have been brought over to Canada in the early 20th century. Both these species are now widespread. The European Common Blue seems to be well established near Montreal, and is spreading. The jury is still out on the (European) Peacock Butterfly - they're only seen sporadically ( again, in the Montreal area ). We usually don't get too upset about new butterflies because they usually don't become pests ( Cabbage white is an exception ), but they can be just as invasive as other critters. We don't necessarily know what impact they'll have on our native species.
RE: kids running wild in the butterfly conservatory - well, it's hard to fault kids getting excited about butterflies. I understand completely.
The obvious solution is to get out and explore the wilderness - off the beaten path. You're blessed where you are - you can practically shoot butterflies outdoors 12 months of the year. It's more of a challenge, but with a bit of effort, you can get photos of species that not many other people ever see, let alone photograph. Of course, being in the wilderness doesn't guarantee that other people won't interrupt your shooting. In fact, that shot I posted earlier of the Northern Blue was an absolute nightmare. The first one I'd ever had the chance to photograph, and all these hikers were barging past me, paying no attention to the fact that I was obviously trying to photograph something.
Stupid other people!
