warped flies in the Lumbridge Catacombs, which can only be entered after completing The Blood Pact. An attempt to take the jade demon statuette will result in a level 5 Warped Fly attacking you. You, however, do not need to kill the Warped Fly to take the statuette. It's has no known use, but you can sell it Xenia for 100 coins. If you do choose to sell it to Xenia you will not be able to get it back from the Catacombs.
