i get mine from a site called bodykind online a tad expensive tho,you can use it to feed to your crix and you can even breed waxies in it,try it,get a nice container,i use a bit of light fabric and a rubber band to keep the moths in and to allow them to breath,put a thick layer of pollen in the container then some wood shaving on top,in go your moths,leave in a warm dark cupboard and leave alone for a month or two then go have a look and you will have 1000's of babys
