Nutrition process

Oral apparatus mosquito contains 5 special needles, 4 stings, proboscis for blood sucking. Each part of the oral apparatus performs its functions. Initially, the pest bites through the skin with powerful mandibles, then it releases the needles. Two of them have sharp setae - about 50, which are commonly called mosquito teeth. They help make the wound deeper, literally tearing the skin. The remaining needles push the epidermis apart, preventing the wound from closing.
