Do your cats eat bugs?

I don't know what my cat eats when he's out on his own, but inside the house he does pounce if he sees a spider or a moth.

Where I live, in late summer there can be a lot of crane flies, also known as daddy-longlegs, coming in through open door and windows. I remember one time my cat pounced on one and ate most of it, leaving just one long leg twitching on the floor. Ugh.
