Tamed Lymantrias make excellent base buddies. They are slow and agile - making them ideal for offloading dinos and building tall bases. They can also easily land on a target 1x1 square, and usually stay on that square if you need to turn while landed. This particularly is useful for reloading turrets or placing that last ceiling. For low level base buddies, level weight and stamina. For high level base buddies, only level weight.
Sounds unlikely but quite true...I own a high level moth with beautiful scarlet wings. It was following me set to attack target when I encountered 3 raptors & a carno. While I was piking the rappies to death my lymantria actually killed that carno plus harvested its meat & hide. AWESOME little beast❗
With teamwork, it can be used to help tame other animals. One team member on Lymantria, the other ones shooting tranq. The slow effect is 90%, therefore, plenty to slow down any creature enough for a person to type it while shooting tranq shots.
