Oak silk moth

The Oak Silk Moth is a large moth found on trees during the summer nights. It can be caught in the rain as well as on clear evenings. It is a relatively rare insect. In City Folk, it makes a distinct flapping sound when disturbed from a tree, which can be startling for players walking around unaware of its presence.

It's real life appearance is quite unlike what it appears as in Animal Crossing.

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 Insect 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."
