May and June are the harvest season for caterpillar fungus. Tibetan Nomadic yak herders and farmers leave their home and set up tents near the mountains for the harvest. They collect the caterpillar larvae with its parasitic fungus whole from the ground. This highly prized medicinal fungus has mostly been traded to China for centuries. During the short harvest period a prolific harvester can earn more than enough cash to live on for an entire year. In the last few decades harvesting caterpillar fungus has developed into the main source of income for rural Tibetans.

Every spring business traders from China travel to Tibet to collect caterpillar fungus from local people. The Chinese grind up the fungus and sell it as a powder, use it whole as a garnish, cook it with soup and drink it with tea. It costs 30-70 RMB for a single caterpillar fungus, though it also depends on where and who you buy from. It’s cheaper if you buy from local Tibetans and more expensive if you buy from shops in mainland China, due to the processing and packaging. It’s better to get local people’s help if you want to purchase some because there are fakes in the market.
