Yeah I meant to put bees wax , anyway I was thinking as honey bees are part of their diet in the wild which in times of low or no flowers they consume the honeycomb, I Done know . Anyway back to flies lol so after reading black soldier flies mouths do not have the same structure as other flies meaning they consume more liquid food rather than solid ,nectar . So as my boy loves the bsf ( or switches on in my opinion) maybe either keeping some bsf in with some hibiscus and nasturtium, or exchange some plants in the viv for the aforementioned plants .
