14th Annual Smithsonian.com Photo Contest
On a trip to Thailand we visited Pang Sida National park which is home to old growth Rosewood and a stunning array of butterflies. There has been a decline in the variety of plants that the butterflies feed from which has prompted the forest rangers to provide a feeding slab to augment the butterflies diet, especially in the dry season. This slab is a large area of bare stone where they run water from a hose. As the water trickles past nutrients that are spread out on the slab, butterflies will gather to suck up the mixture. Many of the butterflies will feed for 10s of minutes, and take in so much liquid that they expel relatively large quantities. In the background, you can see a jet of several droplets being expelled.
