The Oak Silk Moth (ヤママユガ, Yamamayu?) is a large moth found on trees during the summer nights. It can be caught in the rain as well as on clear evenings and nighttime's. In Animal Crossing: New Leaf, it can also be found on the island's fruit trees during the same time of day as on the mainland. In Animal Crossing: City Folk, as well as Animal Crossing: New Leaf, it makes a distinct flapping sound when disturbed from a tree, which can be startling for players walking around unaware of its presence.

Donating to the Museum

In Wild World

"...Ah! I just looked directly into that silkmoth's fabled eye-spots!...I'm unsure what predator would be fooled. Those look nothing like owl's eyes. Ah. Hm. There I go again. Letting my revulsion taint my scientific analysis... The eye-spots DO work, and are a vital evolutionary step! ...But blech."

In City Folk

Upon donating to the Museum, Blathers the curator will say;

"While the oak silk moth has impressively large wings, it's said that this moth isn't a very skilled flier. ...I should think that might be the reason it developed such big, vulgar eyeballs..."

The oak silk moth can be found on the second level of the bug exhibit, in the middle segment with the easternmost stump.

In New Leaf

In New Leaf an information board in the bug exhibit will list information about this bug.

"Oak silk moths are seen in the summer and are one of the largest moth species in the world. They make silk from their mouths as they transition into the pupa stage. As adults, they don't eat anything and only live off the nutrients they stored while they were caterpillars."
