Yeah we do, they are called grasshoppers.
Oh, I don't have a favorite food item. I feed what I have to, to whoever I am feeding. If its a little guy like a dart frog or froglet, then its fruit flies, small crickets, and bean weevils. Other frogs and salamanders and frogs get crcikets mostly and occasionally mealworms or wax worms. The real big guys get lots of crickets the occasional super worm or small mouse. Snakes get the appropirate sized rodent.
