Lymantrias are occasionally found around water sources in valleys. Lymantrias can be identified from far away due to the green spore clouds that the shoot out when they are attacked.

You can bola them
Found in white clifs

It's a big moth, which means all you've got to do is drop a load of cloth clothing on the floor and they'll come and make giant holes in it NUM NOM NUM!

You can find it near chalk hills by a lake
