Oriental Flower Beetle (Protaetia orientalis, 凸星花金龟).
Common summer beetle, usually they are copper or metallic green or something in between those two colours. They are fairly distinctive, but one can distinguish them from other scarab beetles by the narrow white line on either side of the pronotum and the white spots on their backs (dorsal surface). They appeared in droves during the wet part of summer and their bodies litter the ground later in the dry heat. They are fungivorous, and seem to frequent a wide range of flowers and ripened fruits.
