Can you knock a fly unconscious?
Sure. An insect can be rendered immobile by reducing the oxygen concentration (such as flooding the chamber with carbon dioxide, nitrogen or other non-toxic gas), exposing it to an anesthetic (such as ether or chloroform), or chilling it (such as on wet ice).
Can mosquitoes bite while flying?
Once a suitable host is located, a biting fly inserts its piercing mouthparts, lacerates the skin, then injects its anticoagulant-containing saliva to keep the blood flowing. In sensitive individuals, the fly’s saliva can trigger life-threatening allergic reactions.
