Emerald Euphoria (Euphoria fulgida)
At the edge of a dense mixed forest. It was not happy to be on the hot ground in full sun. I think it may have been overheating as it began vibrating its wings and elytra rapidly whilst moving toward a shaded area. It ceased this behavior once it reached shade.
''Euphoria fulgida'', the emerald euphorium, is a species of scarab beetle in the family Scarabaeidae.
