A very clever mod to ease the pain of tearing off the wings of butterflies by simply catching them in a jar instead.  You can still use them for alchemy along with 4 other critters that can be caught in the jar as well. The author is wanting to add the blue butterfly and could use some assistance from other modders to achieve this.  If you can help out, please let the modder know.

The mod only works for the five bugs in jars:
Bees
Torchbugs
Orange Dartwings
Monarch Butterflies
Luna Moths
