Meanwhile, in China - specifically in Sichuan Province:

What appears to be the world’s largest flying aquatic insect was discovered earlier this month in China’s Sichuan province, officials there say.

According to the Insect Museum of West China, an expedition to the outskirts of Chengdu in mid-July returned dobsonflies with 8.3-inch wingspans and “giant snake-like fangs.” Previously, the largest-known aquatic insect was the South American helicopter damselfly, which had a wingspan measuring 7.5 inches.
