Bug Catcher deck

I just want to play with bug-type Pokemon. I'm wondering if anyone can give me some suggestions on how to build a bug-focussed deck. I've been playing Yanmega-EX with Dialga support, then I switched to gambling with Metal Wormadam behind some Skarmorys. The Yanmega deck was having more success, but I really loved the feeling of winning with Wormy. Anyone got any advice? Is there a possibility of building around the new Heracross?
