Mimic Flies are predatory Tundra insects related to Frostsprites. They get their name from their manner of attracting prey. Swarms exhibit highly coordinated actions between their hundreds of members. A swarm of mimic flies clusters together and takes the appearance of something it has previously consumed. They then wait for another creature to approach it, then consumes them.

A swarm, posing as an injured pony, almost eats Lozenge shortly after her escape from Baltimare.

In FearmakerEdit
