I got some questions for food.

I've been trying to feed my frog earth worms, but he/she doesn't seem too enthralled by them. The second day I had the frog it ate a bunch of them, but now I can't get it to eat them anymore. It hasn't eaten since that day which would probably be close to a week now. The frog totally looks hungry and has emerged from the burrow it dug. I tried offering the worms again this morning, but doesn't look interested once again. What do you guys use as staples? I know dubia's are a good option, but I don't think any pet stores around here carry them. What is another prey item I could feed? Keep in mind this is an adult we're talking about. I'm just curious as to what the menu looks like for your frogs, and what they seem to like best, and feed most consistently on.
