Where silkworms appear as food

Eating insects is an ancient custom in various Chinese cuisines, but the modern issue of soaring rent has led to a revival of dining on silkworms in Wuzhen.

Qian Linqiang and his wife, Ni Xingfen, once made a fortune running a small restaurant in the touristy town in Zhejiang province. But 30 percent year-on-year tourism growth since 2009 has pushed up property values.

Their business faltered. They didn't offer picture-perfect "food porn" but rather "authentic rustic" fare.

So, the couple moved their eatery, Family of Silkworm Keepers, to Ni's home village, a small settlement 40 minutes' drive from downtown, in 2012.

They set up the restaurant in a two-story factory once used by Ni's father, who owns a small silk-quilt plant.

Business wasn't good in the first few months.

"I think we had more silkworms and other bugs than diners back then," Ni recalls.

The solution, it turned out, was to fry the pupae to feed people.

"It's like a calling card to lure people to our restaurant," Ni says.

The gregarious woman takes care of "everything outside the kitchen", while her more reserved husband works the woks.

Indeed, these creatures have long influenced local life.

The area claims to be the source of the world's earliest known silk artifact.

And silk continues to dominate the local economy.

Silkworms were a traditional snack, for lack of sufficient nutrition in local diets, until the economy picked up about two decades ago.

Silk comes from the creature's cocoons. The pupae inside are edible.

Yet China's 1 billion yuan ($150 million) silk industry today discards 500,000 tons of pupae.
