Lucanus elaphus larvae care

[Boiseyidaho]

Is there a specific depth of substrate required for lucanus elaphus larvae? I have a lot of substrate for each larvae but it’s spread out in slightly less than 4 inch tall containers.

4 inches are fine enough. I emerged major male in a food jar that is about 6 inches wide (diameter) and less than 4 inches tall. As long as your container is taller than around 3 inches, Lucanids are okay in height-wise.
