Lantern fly

''"I caught a lantern fly! But... where do I put the kerosene?

Upon Donation
Upon donation to the Museum, Blathers says, "It's said that a diet of sap from the lychee tree makes the bodily fluids of the lantern fly sweet. It's also said the proper way to try them ist o break off the tips of the horns and sip them like straws... It's ALSO said that anyone who does those things is officially googly-boogly out of his or her mind."

The lantern fly can be found in the top-most level of the insect section of the museum, perched on the first cedar tree, next to the sign.

Further Information
With alligator-like heads and mothlike wings, these are actually cicadas.
