Thousands of butterflies gather on the ground after heavy rain in Phitsanulok, central Thailand, on June 8.
The insects descended on the area outside the temple in damp conditions following a monsoon downpour.
The white creatures were filmed fluttering around as Buddhist monks and visitors watched them settle in several clusters on the ground.
Onlooker Supachai Worathirasathit said: ''I was going for a trip in a cave and I saw this nearby.
"I was very lucky to go at the time this was happening because it doesn't happen a lot.
"Only during the months of May or June when there is rain.''
