Undermoth
Sold by Underlight Queen. Undermoths are known to be some of the most intelligent moths on Azeroth. This is not saying much. Flying type. Found it as a backline pet in Azj-Kahet at 74.18, 82.15. It doesn't appear to be on the safari list for wild pets.
The Undermoth is a wild battle pet from The War Within, found in Zaralek Cavern and described as one of the most intelligent moths on Azeroth — which is not saying much.
