This is a fermented substrate mat made from 100% oak sawdust, which rhinoceros beetles and stag beetles prefer, and finished with the highest quality Himalayan Oyster Mushroom mycelium.

We've further refined the regular Himalayan Oyster Mushroom mat into a finer particle size for easier consumption, and added 3 times the usual amount of special amino acids like trehalose, glucose, chitosan, and royal jelly, along with symbiotic bacteria, to create this special premium mat.

We use absolutely no discarded substrate, and have meticulously undergone 3 rounds of fermentation, investing significant time and cost to create this ultimate,こだわりのmat.

Since we ferment new substrate indoors, there is a 100% guarantee of no mixed-in pests.

We've received many repeat customers thanks to the consistently large individuals being produced.

Even with the same substrate, mats finished with Himalayan Oyster Mushroom mycelium are the most preferred by stag beetles and rhinoceros beetles, leading to larger individuals.

Himalayan Oyster Mushroom is expensive and difficult to obtain.

This mat can be used as food for the larvae of all types of rhinoceros beetles, both domestic and foreign, as well as for egg-laying.

Not only Hercules and Caucasus, but domestic species will also grow to enormous sizes.

Hercules have successfully emerged at 180mm, and many domestic species have emerged at 87mm.

This high-calorie, nutrient-rich fermented substrate mat is the pinnacle of larval food.
