Desperately Seeking Butterflies!  

This quest is given by Elowys Laceleaf at the docks in the Thundering Steppes.

She is attempting to complete a collection but seems to be missing a butterfly wing. She asks you to find one for her. You can forage these or buy them from brokers. They are foraged in the lower level zones near Qeynos.

When you bring it to her though she complains that it is no good and asks you to bring her a different one.

After bringing her the replacement she'll ask you for a different butterfly wing.

The reward is a small collector's pouch. This then opens up the Desperately Seeking Moths quest (see related quests).

Note: You must bring these one at a time and cannot have the others in your inventory when you do the turn in. If you get there and you've got more than one, try selling the ones you don't need right now to a vendor, then buying them back after the turn-in.
