I'm going to try a meal worm tomorrow, if that doesn't work I'll let him go like I planned. He grabbed at the cricket and gave it a good gash on its abdomen but the cricket escaped the beetle's pincher.
It sounds mean, but how I do that is I just squish the cricket a little bit with my tweezers. My tiger beetle and my ground beetles wouldn't eat unless I did this for them.
Well this guy got the cricket even though it was alive. He tore it to shreds, there were little bits of cricket all over the cage. It looked like it was an vicious death! I missed it though. I was out of the room. =(
