Cyclommatus stag

The cyclommatus (ホソアカクワガタ, Hosoakakuwagata) is a stag-looking beetle with large mandibles introduced in. They almost look like a strange, oversized Giant Beetle. They are found on palm trees and sell for 8,000 Bells. The months of the year they are found in is June, July and August. They are found from 11 pm to 8 am.

Donating to the Museum in City Folk
Upon donation to the Museum, Blathers the curator will say,

"The calling card of the cyclommatus is its pair of mandibles, which are usually as long as its body. Another interesting fact is that the bug hates heat and will usually perish in a non-air-conditioned room. I can sympathize, eh wot? Leaving the sanctum of the museum for the summer heat is simply wretched."

After donation, the cyclommatus can be found on the second tier of the insect section, in the large enclosure on the middle palm tree. This enclosure also contains the rafflesia, tarantula, scorpion, and elephant beetle, to name a few.
