I believe that most people will feel disgusted when they see the dish " Water Cockroach ", which is indeed normal and understandable. But can you think it is a "hard dish" that costs nearly 100 yuan per plate on the dining table of southerners?
We call this insect Dragon lice . It looks very much like a cockroach, so it is also called a water cockroach. In restaurants in some places in the south, the trellies are sold at two or three or three, made into salt or boiled with pepper or water, and a plate costs sixty or seventy yuan.
In fact, the scientific name of "water cockroach" is Dragonfly, also known as Water Tortoise, which is aquatic insect . It is a collective name for all species of species of the family . It has a huge family, and there are about 160 species in our country alone.
"Water Cockroach" is larger, with a body length of 3.5~4 cm, oval, flat, shiny, and some species have stripes or dots. The whole body is black, the side edge of the sheath is yellow, and the black part is bright green. Compound eye is located behind the head, close to the front edge of the chest. The base joints of the front and middle feet are small, the hind feet are well developed, the side is flat like a paddle, the matte hair is long, the base joint is wide, and it is in contact with left and right. It is tarsal joint 5, suitable for swimming.
The tarsal segments of male insects forefoot are flat and wide, with adsorption effects, and are used to suck on the back of female insects during mating, in order to hold the feet.
Aquatic cockroach larvae and adults are aquatic [1], prey on small fish, shrimp, tadpole and other aquatic animals, laying eggs on the branches and leaves of aquatic plants. The larvae have slender bodies, large heads, 6 pairs of eyes, short antennae, 6 to 9 nodes, sharp and curved upper jaws, and have pores inside, which can absorb animal juice. There are 3 pairs of thoracic feet. When the larvae are old and mature, they enter the soil by the water to pupate, and then gradually degenerate into adults.
Adult dragon lice are very cruel and are too domineering in carnivorous. It is said that it is fierce because it not only eats small fish, shrimps, insects and tadpoles, but also fish and frogs that are several times larger than themselves will attack and prey. It is not surprising that they eat more than 10 tadpoles in a day and night.
Dragon lice are both cruel and delicious. Do you dare to put chopsticks with such deliciousness?
