Quercus acutissima, Quercus serrata wood, fine particle additive-free mat, 5L x 5 bags

This premium-grade substrate is recommended for larval rearing, egg-laying, and stocking.

It has achieved excellent results in the egg-laying and rearing of most stag beetles. We have used it for egg-laying and rearing of species such as *Dorcus hopei binodulosus*, *Neolucanus swirei*, *Prismognathus davidsoni*, *Prismognathus subaequalis*, *Dorcus* species, *Prosopocoilus* species, and Rainbow stag beetles, and they have been laying an astonishing number of eggs, even laying them at the bottom of the rearing case.
