Mosquito

Mosquitoes are small insects that spawn from ponds at dusk and night. They are fast-moving and aggressive, attacking anything nearby. 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 sac which grows with each successful attack. When the sac 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. Holding space bar is recommended because the game targets the mosquito for you.They also do not drop any items, meaning that killing them generally only helps in a defensive situation.

Trivia

 * Mosquitoes originally spawned from the same ponds as Frogs, but now each spawn from separate, different colored ponds.
 * Mosquitoes and Frogs are natural enemies, much like Merms and Pigs, and will fight if they encounter each other.
 * Mosquitoes will not spawn during winter, due to their pond being mostly frozen over.
