My local zoo has a butterfly enclosure where you can find these magnificent creatures year round. It gets pretty humid inside this place so its tricky in the winter if you've been shooting outside once you go in here your lenses will fog up and take about 20 minutes to defog. It is well worth the wait though as there are many different species of butterflies many calmly perched all over the enclosure.
