found them under slightly rotting logs and they are HUGE!


I think you should use the same wood that you collected larvae from.awesome!
i am kind of confused what kind of substrate to use for them and i cant find any care sheets online for them
and i know people offer dogfood and fruit to dynastes larvae to eat do stags also benefit from this?
No, the sutures on the face are very different. Also the head coloration is different but that's not definitive.Larvae of the four US Lucanus species look exactly alike.
