Hi everyone I would like to tell you how I breed species of the genus Lucanus: It is very important that you can fill at least 25 cm of substrate into your breeding container. I put 5 cm of earth on the bottom and I lay big pieces of white rotten wood on it. Then I put about 10 cm of Flake Soil (fermented wood) on this. The rest is filled up with humus and rotten leafs. It should be kept humid and cool at about 15-18°C. I feed the beetles with beetle jelly. After the beetles die, I wait another few weeks and search for larvae. Searching for eggs is rather dangerous because they are very sensitive to pressure. I keep each larva in a container of 500 ml - 1 litre with pure Flake Soil. A japanese friend said, that protein is not necessary to get big imagos. The beetles normally hatch after 2 years and become active during early summer of the third year, when they are kept at 15-18°C. When they are kept to warm the larvae could die or you will get small beetles. The picture shows a freshly hatched male of Lucanus maculifemoratus maculifemoratus Attachments:

Thanks for sharing, I am wandering how I can apply this to my lucanid breeding (lamprima) if at all???
actualy 25 cm of substrate is quite a lot ...

Bichos, breeding of Lamprima is a bit different from Lucanus. Lesser substrat depth works perfectly fine, and you would also not need any soil. A wood only substrate is much better. What species are you breeding? You should have access to some really rare beetles :-)

Yes it's different indeed and no you dont need any soil at all. However the biggest lamps I've ever seen including a 35mm male have come from partially buried logs in fertile soils, so that is why I'm thinking that i can do something similar now that I've read your lucanus technique. I can do something similar and it should work for lamps too. What am I breeding? Just muelleri and lamprima at the moment. I need more lifetimes to do all the breeding that I want to do.

Very nice pupae indeed, is it a bit risky exposing like this? Les us know how they turn out. Is it judaicus or akbesianus???

It's not that risky, you have to get the right moisture level and everything is ok. Usually I let them develope in their cocoons but the substrate in their containers got moldy so I got them out of there. The upper two ones are judaicus the bottom ones are akbesianus. One of the akbesianus males will hatch very soon. I'll post pictures then

Fantastic specimens, good sizes, nice and fresh, shame about the damage though. There is a malleable foam-like green material which can be used for large pupae, I believe it is used for flower arrangements or similar.Perhaps you can try it or something similar.

Yes this is used usually for keeping pupae but I thought it would also work without it. It is only important that they are able to turn themselves properly.

THANKYOU, ofcourse and that is why you sometimes get damaged lucanids which have pupated on the bottom of glass jars, as they have been unable to get a grip and turn over...

The judaicus turned out with 92 mm and 97 mm

just wondering, how many years it takes from egg to adult ?

2 years in breeding conditions. They need longer in the wild because the larvae hibernate which they don't do at constant breeding temperatures
