Chrysina gloriosa

Recently my trio of C. gloriosa all died, I checked their breeding box and my female left me with 9 eggs. I was wondering if anyone has had experience raising these beetles and how long it takes for this species to become a beetle from an egg?

I've heard from several people that have mentioned successfully raising the grubs on hardwoods, especially sycamore. I heard it was an extensive larval period - I want to say 9-12 months but it could have been longer.

 
Greatest adult longevity for gloriosa is achieved by feeding them Juniper, which is their natural host tree. I've had adults live for at least two months, when given Juniper. The particular species of Juniper doesn't seem to matter, but I've always used Juniperus ashei. In SE Arizona, they feed on J. deppeana.
