the fly food from Rebecca is a gutload. it contains powdered milk, sugar, and a touch of bee pollen. the flys need the sugar, or if a wet gutload, I prefer using honey.Thanks. And, Yeah - I use both - I even got the Yen's Blend FROM Rebecca, but I honestly forget which one is supposed to do what. I've never actually dusted the flies like I would a cricket. Hmmm....
I have no idea how good powdered honey would be vs. say real honey as a gutload.
it is my understanding that Yen's blend is to be used as a dusting for feeders that are to be fed to flower mantids. yet I see no reason it can't be used as a gutload too. just maybe not as good as say the fly food or a good wet gutload.
