Tiger butterfly

The Tiger Butterfly is a common butterfly that can generally be seen during the Spring and Summer months. Contrary to its typical flower-loving brethren in, in and  it was only found flying in open spaces away from places, however in  and  it was found near red flowers. In the GCN games they are fast and hard to catch, but in and beyond slowly, therefore can be caught more easily. The name "Tiger Butterfly" can be confused with the real life Tiger Swallowtails of North America, but it is actually a seperate species known as the "Old World Swallowtail" or simply "Swallowtail".

Donating to the Museum
As with all fish and bugs in, the Tiger Butterfly can be donated to the Museum by talking to Blathers, who will also tell the player a little bit about the donation. Regarding the Tiger Butterfly:

In Animal Crossing
Blathers response upon accepting butterflies for the museum in Animal Crossing is the same for all species:

"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!"

In Wild World
Blathers will accept Tiger Butterflies for donation to the insect room of the museum, but this doesn't necessarily mean that he likes them:

"Tiger butterflies are named due to their distinctive tiger-like markings... I must say, I'd almost rather encounter a real tiger than one of these. Real tigers are nowhere near as... wretched."

The Tiger Butterfly can be found hovering around the flowers in the first room of the insect exhibit after donation.

In City Folk
After donation at the museum in City Folk, Blathers the curator will talk about the Tiger Butterfly:

"Aside from the South Pole, one can find Tiger Butterflies just about anywhere on earth. Imagine these monstrous bugs flapping about the whole globe... The very thought robs me of sleep!"

The Tiger Butterfly can be found fluttering around the flowers on the lower tier of the insect room after donation.

Further Information
Papilio machaon, the Old World Swallowtail, can be found throughout the continents Asia, Europe, and North America. The name Old World Swallowtail comes from the fact it was first described in Europe, where it is simply known as the Swallowtail due a lack of other Papilio species in the area. There are over 30 subspecies of Old World Swallowtail, differing in habitat, intensity of yellow colouration and markings. In most areas they are common, but some subspecies, such as P. m. britannica of the English Norfolk Broads are endangered. In North America the general habitat is dry grasslands and hilltops, in Europe it is wetlands and marshy locales and in Asia they inhabit meadows and hedgerows. The adult butterflies are around 80 to 100 mm in length.

Caterpillars are green with black stripes, and feed off of Milk Parsley, Fennel and related plant species.

True Tiger Butterflies are a purely New World species that are much larger and differ from the Old World Swallowtail by having more striped wings and a more triangular wing shape. True Tigers also have a different foodplant, which tends to be those of the Citrus family.
