I want to know too, I have collected some a few weeks ago, but from the look of it, I don't think my rhino roaches would like them, so I didn't feed those leaves to my roaches. But then I saw these trees are infested with bugs, so I guess it can't be bad to rhino roaches, and that's why I collected them. I'll probably feed those leaves to my peppered roaches first see if they like it, they seem to like dead leaves a lot.
