There are plenty on Warrior Wasps in the area if you know where to wait. Most of the ones i have killed were near the orc hill. But to no avail, only Wasp Winds and Venom Sacs. I've been trying these kills for the Pollen since 5th level and now I'm 15th. I think that the quest is a dead one now. I think that they want you to do the PoK quests for the armor, seeing that you get a piece of Art Keepers Armor for every Note you give your guild.
