Hello, All. I have L3 Goliathus goliatus and, of course, my mind is occupied with preparing the proper substrate for the day they go a-wanderin' before cell prep. Karl Meier (http://www.naturalworlds.org/goliathus/manual/Goliathus_breeding_4.htm) has it 60% sand/ 40% peat; however, I know that some use red clay. I would be interested in others' formulae as I am developing mine.
