-- The largest recorded aquatic insect in the world was found in China.
Measuring at eight inches in wingspan and with a giant set of mandibles at its head, the flying dobsonfly is roughly the size of an adult human face, according to the Insect Museum of West China.
Some other large insect facts: dobsonflies do not typically grow to be larger than five inches in width, according to the Missouri Department of Conservation. The mandibles in male dobsonflies can make up for half of their size.
Male dobsonflies are harmless but the females have a pair of pincers that can cause painful bites to humans. Neither the males or females are venomous.
Adult dobsonflies typically live up to one week.
They are commonly found in the western hemisphere, Asia, and South Africa.
