I rate the humble silky as my favourite feeder, both nutrition wise and ease of keeping/breeding.
Moths are fine to feed as a supplement feeder, i've been doing it for ages (mainly other herps) with no problems at all.
I just spent 3 hours on the weekend going to my mulberry tree, which is in the bush a short drive from my house, to come home and sort out the leaves, fold them up and store them... it's a labour of love! lol
Cheers
Scott.
