Hello! I came across this giant recently (in Malaysia) and can't find any answers. Was thinking some kind of scarab beetle but doesn't really look anything like these. If anyone has any idea what type of insect this might be it would be appreciated. Wingspan about 8cm, very hairy underneath, lots of armor, sounds like a buzz bomb when it flies! Didn't seem too aggressive when I was taking photos. Many thanks.
