Chrysina beyeri & gloriosa

Some photos of my Chrysina beyeri and C. gloriosa - two of the four species in this genus that are found in the US.  The other two are woodi and lecontei.

Absolutely gorgeous!

Chrysina beyeri larva in 16 oz. container, in pupal cell formed in clay layer, below the organic substrate layer.  In this species, cells are nearly always formed right against the container wall.  Because of this habit, the larva remains visible through a small "window" while in its winter diapause stage, but will become obscured following pupation, since in this genus, the shed pupal skin expands to form a loose, paper-like envelope around the pupa, rather than being wadded up and pushed to the back of the cell as in Dynastinae, Cetoniinae, Lucanidae, etc.

Does this species go through the diapause even if kept at room temps?
