Dytiscidae

Dytiscidae (known by various common names around the world, including predaceous diving beetles, water beetles and diving beetles) is a family of water beetles. They are about one inch long, dark brown in color with golden highlights and short, but sharp, pincers. The larvae are commonly known as water tigers. The family has not been comprehensively cataloged since 1920, but is estimated to include about 4,000 species in over 160 genera.

When still in larva form, the beetles vary in size from a half an inch to two inches. Their bodies are shaped like crescents, with the tail long and covered with thin hairs. Six legs protrude from along its belly, which also sports the same thin hairs. The head is flat and square, with a pair of long, large pincers. When hunting, they cling to grasses or pieces of wood along the bottom, and hold perfectly still until prey passes by, then they lunge, trapping their soon-to-be-food between their front legs and biting down with its pincers. Their usual prey includes tadpoles and glassworms, among dozens of other smaller water-dwelling creatures.

As soon as the beetles come to the stage in life in which they mature to adulthood, the larva crawl from the water on their aforementioned sturdy legs, and bury themselves in the mud for around a week; upon the end of this period, they emerge from the mud as adults.

They are eaten in the Canton area in China.
