Thanks for this. I've been dealing with it for a few months now.
The only way I've been able to get Mr. Puff to eat dubias anymore is to release them on a branch and chase them back and forth with the tongs and it can take a while.
Otherwise he just sits and watches the dubias like TV for hours and doesn't eat and I eventually just put them back.
If they were super worms, he'd crawl across the house just to get to them.
I'm trying out putting a ton more dubias in the cup hoping they keep his attention.
