Dear Iawa,
This is a Scarab Beetle in the genus
Osmoderma and according to BugGuide, the larvae feed on: “Decaying centers of various hardwoods.”  Is there a rotting tree nearby and did the beetle smell like leather?  We believe this is Osmoderma eremicola which is commonly called a Hermit Flower Beetle or the Odor of Leather Beetle because according to BugGuide, it gives off a “strong odor of ‘Russian Leather.'”  BugGuide also notes:  “adults nocturnal, come to lights.”
