In detail:
- if a Mosquito is touching more than one other piece, it can take on the movement characteristics of any one of the pieces it is touching
- if a Mosquito is only touching another Mosquito at the start of a turn, it may not move at all
- a stack with a Beetle on top counts as a Beetle, i.e. a Mosquito touching such a stack cannot take on the movement characteristics of any of the pieces hidden under the Beetle
- if a Mosquito is moved as a Beetle onto the top of the Hive, it then continues to move as a Beetle until it climbs down
