Help Identify Carnivorous Taiwanese Beetle

[beetlebug]

I wassearching for japanese rhino beetles (allomyrina dichotoma?) under logs in Maokong, Taiwan. Under a log I came across what looked liked a dung beetle eating a live caterpillar. I took it home and the beetle ate the entire caterpillar.I was unaware that dung beetles were carnivorous, so im not sure it is a dung beetle. heres a pic and youtube link. sorry about the lame music, my friend uploaded it. Beetle experts, please identify it. Thanks

Looks like a beetle in genus Eophileurus. Adults are known to feed on other insects. Your specimen appears to be a female so if you still have it, you might want to give a shot at breeding it
