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!Has anyone had any experience rearing the 10 lined june beetle? If so does anyone have any tips on catching them?
Adults only live for a few weeks; not much longer than a month, probably.Hot damn! How long is their life as imagos?
Live roots could perhaps be mimicked? Something similar to mung bean saplings?
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!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.
