Mosquito

Mosquitoes are small insects that spawn from ponds. They are fast-moving and aggressive, attacking both Wilson and other nearby animals like Frogs. Mosquitoes take one blast from the Ice Staff to be frozen. Although they deal a relatively small amount of damage, these insects are usually found in groups and can quickly drain away health. They have a small red blood sack which grows with each successful attack. When the sack is full the Mosquito will explode causing additional damage.

Hunting
The most effective way to deal with Mosquitoes is to capture them in a Bug Net. When used this will turn the insect into an inventory item, although it has no use in crafting. Due to their fast flying speed, Mosquitoes are difficult to hit with melee weapons. They also do not drop any items meaning that killing them is only useful in self defense.

Trivia

 * Mosquitoes originally spawned from the same ponds as Frogs, but now each spawn from separate, identical-looking ponds.
