Well, he refuses anything I've dusted so far. This is one juvenile pacman (C. cranwelli). The only thing he'll take consistently is nightcrawlers - and I think that's actually because I'm too afraid to dust them in case he starts rejecting those when they're dusted, too.

Rejected food: dubia roaches, phoenix worms, and he refuses mealworms/superworms and waxworms if there's even a hint of dust. (They are all occasional items introduced at irregular intervals. I like to give a variety where feasible, and it was surprisingly easy to culture those guys.)

I hate dealing with crickets, so they are a very occasional treat.
