The Raja Brooke Butterfly (アカエリアゲハ, Akaeriageha?) is a rare bug that was introduced in City Folk. and is found near fresh water. It is the only butterfly to be attracted to water, but another bug, the Firefly, shares this trait. Most believed this was just a summer butterfly, but rarely it can be found in September.
Donating to the Museum
In City Folk
"...I must say, I'm quite impressed with your ability to catch such an impressive butterfly... The Raja Brooke butterfly, I must tell you, is one of the larger tiger butterflies. Naturally, its antennae and proboscis also rank as some of the largest around. Be not proud, vile beast! Your cute red collar and fancy name do not fool Blathers!"
It can be found in the bottom-left enclosure in the bug exhibit, flying around the pond.
In New Leaf
In New Leaf an information board in the bug exhibit will list information about this bug.
"Raja Brooke butterflies have red heads and a red strip around their necks, giving the look of a collar. They are known to drink hot-spring water and often hang around water flowing up from the ground. While males are vibrantly green, females are much more commonly seen with brown wings."
Once the player has caught a particular fish or bug, they can find information about it in the bug or fish menus. Once the Raja Brooke butterfly has been caught, the following information can be found in the bug menu:

This birdwing butterfly shares a close relation with the better known swallowtails, as noted by Blathers in-game, and with the Parnassius genus they form the family Papillionidae. The Rajah Brooke has distinctive black and electric-green markings, which are more prominent in the males, while the females have white markings. Both have a crimson head and collar. It was named and described by Alfred R. Wallace in 1855, after James of Sarawak (the Rajah of Sarawark). It is also called the Rajah Brooke butterfly, and spelling it as "Raja" is often considered as a mistake though both are acceptable.
They can be found in the rainforests of Borneo and the Malaysian Peninsula, and is featured as the national butterfly of Malaysia. It is registered as an endangered species under conservation protection.
