Pattitarn Tongsiri is silhouetted in his factory, which produces "HiSo" snacks in Bangkok's suburbs February 24, 2015. Street vendors selling deep-fried insects as snacks are a familiar sight in Bangkok, but a Thai entrepreneur is trying to give edible bugs a more upmarket appeal. Panitan Tongsiri will launch his "HiSo", short for high-society, brand of seasoned insect snacks in March and plans to stock them at gourmet food markets around the Thai capital. Crunchy crickets and worms would be a delicacy available in plain salt, cheese, seaweed and barbecue flavours at 25 baht (less than $1) per pack, said the 29-year-old businessman.
