The adults feed on fruit which can very easily obtained but I'm using a specialist beetle jelly from Japan.
The larvae of Prosopocoilus spp. feed on soft-medium decay of white, rotten oak, beech, or sweet chestnut wood but wood (especially oak which is the best for stags) is extremely hard to find here in the UK so to 'increase the volume' of the wood substrate, I add oak leaf mulch. However, this is very low in nutritional content so if they are fed on this mix throughout their larval cycle, the adult males will be very small with minor horns:
(like the adult male on the very right)
... so the larvae need to be transferred to 'Kinshi' (mycelium) bottles once they are larger in order to obtain larger specimens.
But then again, if I were living in Japan (the 'capital' of the countries with beetle hobbysits breed beetles), they have already perfected their breeding substrates and such so I won't have to go through all of this, as they sell ready made substrate and kinshi bottles for beetles in supermarkets.
