This is a question for those of you that are experienced in rearing Lucanus beetles. Just to summarize my limited experience with these beetles, a few years ago I collected a few wild pair of Lucanus elaphus. The females oviposited a good number of eggs in the subsrate I provided. I kept the larvae in separate containers that held hardwood substrate. Nearly all made it to adulthood, but none were of any great size. I am aware that in Japan, breeders regularly get very large specimens. What is their secret? Are the grubs on a special diet? Is it possible to get larger specimens than I am encountering in the wild? Any help would be greatly appreciated. Tom

Hi Tom
The most important thing is, that you rear the larvae around 20°C. Feed them with fermented wood, Flake Soil. It is possible to get bigger specimens than in the wild but than you have to give extra additives to the substrate, like dried Chrysalis of Bombyx mori. Lucanus cervus 70mm+ is possible with Flake Soil only, but 75mm+ or 80mm+ will need additives. Big Males need 18-24 months, females 12 months. Lucanus elaphus should be the same. A friend of mine will try this species soon.
