Selections from a list I found at Learn About Butterflies, where you can view photographs and read about life cycles for many hundreds of species worldwide.
Pictured above is the "Snowflake" from the Amazon rainforest -
Snowflakes are invariably encountered singly, usually when seen in flight at light gaps in the forest, where trees have fallen and sunlight penetrates to ground level. These tiny butterflies have a very slow and very persistent fluttering flight, flying for long periods but apparently going nowhere ! It is in fact possible to watch one of these delightful butterflies drifting and wafting about, but without travelling more than a few metres, for several minutes before it eventually settles.
