Fascinating stuff! Thanks for your answer.

Hello! I recently spent several months volunteering in South America, and for a portion of that I was in the Amazon rainforest. One evening, whilst we were sitting around a single candle as it poured with rain outside, we noticed some odd behaviour - three large ants (two workers and one soldier) were running around and around the candle in very neat circles. We watched them do this unceasingly for at least an hour. Curious, I found that wherever I moved the candle they would follow it and continue then going in circles. It was only when I extinguished the candle at the end of the night that they stopped circling and went off in random directions. Can anyone explain this behaviour?
