Mosquitoes are flying enemies seen in Jungle in Spelunky 2.
Mosquitoes can fly, but will never travel in a diagonal line to do so. If the player is with sight, they will shoot towards them until they hit a wall, at which point they will become stuck for several seconds before continuing. During this time they are very easy to defeat by either whip or jumping on them.
They seem to drop a dispraportionate ammount of blood relative to their size. This makes them good kapala targets.
Rarely drops Hover Pack (Seen in patch notes 1.12.1e)
