A salesperson weighs caterpillar fungi at a caterpillar fungus store in Lhasa, capital of southwest China's Tibet Autonomous Region, June 12, 2014. The caterpillar fungus can sell for as high as 300,000 yuan (48,000 U.S. dollars) per kilogram. However, the price has risen after this year's harvest due to the reduced collection in the region.
