Where there's frost, there are frostflies.
Frostfly is a type of bug which can be caught using a Bug Net. Catching it will complete entry #17 in the Bugs Collection inside the collections library.
They can be found in Snow biomes.
If captured and released using a Relocator they'll fly around instead of being inside a jar. Bugs captured using a Relocator won't count toward the bug catching collection or achievements.
