THE MIRACLE IN THE MOSQUITO






















                                                                         sucking tube





                     One of the knives numbs the tissue
                 with a salivary fluid it pours into the
                 wound. This is a kind of local anaesthet-
                 ic. In this way the mosquito cuts into the
                 skin and you don’t feel a thing as it sucks
                 your blood. As this fluid also prevents
                 the blood from clotting, the mosquito is
                 able to carry on sucking the blood. It is
                 again this fluid that later causes irritation
                 and swelling.


                     The thorax
                     This section joined to the head of the mosquito is where the
                 mosquito’s six legs are appended to, as well as a pair of wings.
                 These wings are covered in scales and have veins passing through
                 them.
                     Some varieties of insect have two pairs of wings. However, in
                 place of a second set of wings the mosquito has stubby knobs
                 which vibrate during flight to help provide stability and balance.
