That would be a great beetle to breed, but like most melolonthine scarabs, the larvae feed exclusively on live plant roots, and it would likely be quite difficult to maintain the right conditions for rearing in captivity. Also, the larval cycle of this species can take up to 4 years! Quote Link to comment Share on other sites More sharing options...
Briareo Posted April 25, 2020 Author Report Share Posted April 25, 2020 Hot damn! How long is their life as imagos? Live roots could perhaps be mimicked? Something similar to mung bean saplings? Quote Link to comment Share on other sites More sharing options...

Something similar to mung bean saplings? Adults only live for a few weeks; not much longer than a month, probably. I think the larvae feed mainly on the roots of trees and shrubs. I'd recommend Chrysina (Jewel Scarabs) as a more practical rearing project than Polyphylla. I've reared three of the four US Chrysina species; the larvae feed on decayed wood, just like those of Dynastinae, Cetoniinae & Lucanidae, and only take a year to complete to complete their life cycle (although, a percentage of larvae have a two-year cycle, instead of one).

Lucanus Posted April 28, 2020 Report Share Posted April 28, 2020 Someone told me that they've been bred and reared in captivity by using clover sprouts and bird seeds. Took them 4~5 years to rear the larvae to adulthood. Quote Link to comment Share on other sites More sharing options...

If it's going to take around half a decade to rear some Polyphylla decemlineata that are only going to live for a few weeks as adults, I can think of a great many other beetles that would be much more worthwhile to keep!

Briareo Posted April 28, 2020 Author Report Share Posted April 28, 2020 Lmao! I agree with that sentiment Quote Link to comment Share on other sites More sharing options...
Djé Posted May 11, 2020 Report Share Posted May 11, 2020 2 correct answers have been given here: Bird seeds and carrots BUT young stages also eats humus/decaying matters I am currently trying to breed Polyphylla Fullo, our biggest and most beautifull melolonthine scarabs For fullo something like 60% of the substrate must be sand Can't believe a second that in good breeding conditions larval cycle will be 4-5 years Quote Link to comment Share on other sites More sharing options...
