Yellow butterfly

The Yellow Butterfly is an incredibly common butterfly that can be found anywhere near flowers. It is worth 80 bells in Animal Crossing (GCN) and 90 bells in Animal Crossing: Wild World and Animal Crossing: City Folk They flutter slowly around town from March to October. It is very similar to the common butterfly, in every way but color. It was the first revealed bug in, with a photo of one flying near a tree. It has appeared in every Animal Crossing game so far.

Donating to the Museum
As with all bugs and fish in, the Yellow Butterfly can be donated to the Museum by talking to Blathers. During each doantion, he will enlighten the player to some information about the donation. Below are quotes from each game, on what he has to say;

In Animal Crossing
Blathers has only a general response upon accepting butterflies for the museum in Animal Crossing;

"There's an old saying among some of my contemporaries: "Butterflies are beautiful, yet moths are monstrous." Well, if you were to ask me, I'd say they were all the same! By which I mean disgusting! Truly hoo-rrific, wot wot!"

The yellow butterfly can be found fluttering around the flowers in the central display in the insect room after donation.

In Wild World
Upon donation, Blathers the curator speaks of the the yellow butterfly;

"Butterflies are covered in "scales" that flake off when touched, eh wot? Blech... The very thought makes my eyebrows itch unbearably... Anyhoo, I suppose that's neither here nor there..."

As with other butterflies, the yellow butterfly can be found flapping around the flowers in the first room of the insect display.

In City Folk
Once again, Blathers will speak of the yellow butterfly in a rather horrified way:

"We call them all yellow butterflies, but many subspecies of this insect exist, wot wot? Indeed, this fact makes them rather interesting to many researchers... What's more interesting to me is why anyone in their proper mind would take interest in these things."

In City Folk, the yellow butterfly appears flying around the flowers on the lower terrace of the insect room.

Futher Information
Pieridae, yellow-white butterflies, are a large family of butterflies that are widespread throughout the world. So common in fact, that many sub-species have been given dozens of names throughout the world. Yellow-white butterflies are, as the name suggests, yellow or white in colouring, and usually have black markings on the wings. Males are generally coloured differently to the females of the same species.

The butterflies shown in Animal Crossing are females, as males lack the yellow spots within the black bands on the edges of the wings. Colias erate is locally known as the Eastern Pale Clouded Yellow and is widespread over eastern Europe and Asia.
