This listing is for nutrient-rich crushed mushroom substrate specifically for stag beetle larvae (19 photos attached above).

10 Liters (Free Shipping)

Comes in a resealable bag for convenient storage.

We can accommodate additional liters upon request.

Up to 100 liters can be combined in one box.

This mushroom substrate is made from 100% Quercus (oak) sawdust, which stag beetles prefer, and finished with the highest quality Himalayan King Oyster Mushroom mycelium.

It has a sweet, mushroomy aroma.

Even with the same mushroom substrate, those finished with Himalayan King Oyster Mushroom mycelium are most preferred by stag beetles, resulting in larger adult beetles.

Himalayan King Oyster Mushroom substrate is expensive and difficult to obtain.

It can be used as food for the larvae of all types of stag beetles, both domestic and foreign.
(Suitable for large stag beetles like Odontolabis cuvieri, Rainbow stag beetle, Dorcus hopei, Sawtooth stag beetle, etc.)

The Himalayan King Oyster Mushroom substrate was produced in a controlled indoor environment, then crushed and bagged.

They eat it voraciously!

The key to raising large adult stag beetles is to feed the larvae plenty of high-quality food during their larval stage.

With good quality substrate, stag beetle larvae will continue to eat heartily!

Their feeding response is different, allowing you to aim for super-sized beetles!

It's versatile for use in bottles, small containers, or mixed with fermented substrate, and is more economical than using mushroom bottles for rearing.

You can also create your own fermented substrate by adding additives to this mushroom substrate.

We also have fermented substrate which is this mushroom substrate fermented indoors for an extended period until it turns black. Please check my other listings.

The black fermented substrate is a versatile substrate that can be used for rhinoceros beetles in addition to stag beetles.

Some users who love the Himalayan King Oyster Mushroom substrate have won top prizes multiple times in Be-Kuwa contests.

Ready to use immediately, no degassing or watering required.

*This substrate is not for making mushroom bottles.

*Himalayan King Oyster Mushroom substrate is precious and the harvestable amount is very small. During peak ordering periods, shipping may take some time.

*The size of the emerged beetle can vary greatly depending on the bloodline and rearing environment, such as temperature control.

For those seeking only size with mushroom-eating stag beetles (Odontolabis cuvieri, Dorcus hopei, Rainbow stag beetle, Sawtooth stag beetle, etc.), I recommend the Himalayan King Oyster Mushroom Bottle listed separately.
