Upon donation to the Museum, the exhibit has this to say about the Giant Cicada:
 * "As the name might indicate, giant cicadas are one of the largest species of cicada in the world. They used to live mostly in warmer western Japan, but they've now also moved to urban eastern Japan. Though they're now common in these areas, they aren't well known in other parts of the world."
