Butterflies can be collected throughout the world and used as monster bait, to craft lures, to complete achievements, or to fill out your almanac.
Need help catching butterflies, visit the Butterfly Trapping page.
Butterflies for Profit[]
(Note - You get 1 exp extra for the act of catching each butterfly along with the exp the butterflies give you. So when catching them, the values you see ingame will be 1 exp higher then the values here and in the almanac.)
