Visited a small nature reserve on the way to work this morning. It’s called Tsurugidake Nature Park and is located near Kurate. At the top of the hill there were a couple of rotten trees that were covered in fungi. On the tree were two specimens of this “rainbow beetle” (naganiji gomimushi damashi), which eats fungi.
Coleoptera: tenebrionidae (darkling beetles)
Ceropria induta = naganiji gomimushi damashi
