Oral apparatus mosquito contains 5 special needles, 4 mandibles, proboscis for sucking blood.Each part of the oral apparatus performs its functions. Initially, the pest bites through the skin with powerful mandibles, then sets the needles in motion.

The remaining needles push the epidermis, do not allow the wound to close.
On a note!
The mosquito introduces a proboscis into the wound, injects a special enzyme that prevents blood from clotting, and facilitates the process of feeding. This substance is a strong allergen, therefore, causes an instant reaction of the immune system to what is happening.
