Donation to the museum

In City Folk

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

"...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.
