Kumazemi
(a photo is uploaded. please check her official site)
There's this type of cicada called Kumazemi(Black Cicada).
The males are from 60mm to 64mm in length. The femals are from 63mm to 68mm. (Hmm, so the females are bigger~.)
They are reportedly living mainly in urban areas.
They reportedly sing only in the morning.
Their buzzing reportedly sounds like "Kuma- Kuma- Kuma-." Which is a lie.
Actually they buzz like "Shaww Shaww" or "Washh Washh Washh."
Humph, that's no fun!
