The Mosquito pieces can be added to a standard Hive set before the beginning of the game giving each player 12 pieces to play with.

During the game, they are placed in the exact same way as the other pieces. Once in play, the Mosquito will take on the movement characteristics of any creature it touches at the time, thus changing its characteristics throughout the game.

Exception: If moved as a Beetle on top of the Hive, it will continue to move as a Beetle until it climbs down from the Hive.
