Sulphur Butterfly

Butterflies can sometimes be approached closely when they're busy drinking from flowers, as this one is – note the straw-like proboscis dipping into the flower's center. In this case, it was too flighty even when feeding, so I followed it for about twenty minutes, moving slowly and shooting only a few photos. Eventually, the butterfly got used to my presence and decided to ignore me, so I was able to get extremely close without scaring it away.
