# Stag Beetle & Rhinoceros Beetle Product List on Mercari ← Click Here!

Thank you for viewing.

Limited Sale!!

This is a listing for a set of 3 used substrate blocks for *Dorcus hopei binodulosus* (Giant Stag Beetle).

Please see the 19 photos above.

These are quite large blocks.

You can add as many as you like!

These used substrate blocks are made from 100% raw oak sawdust and are packed with nutrients.

As you can see in the photos, the mycelium is firmly established within the blocks.

Simply bury the blocks as they are in the substrate, and stag beetles will lay eggs!

They are easy to break apart, making extraction easier than with logs and allowing you to obtain a large number of larvae!

My *Prosopocoilus inclinatus* are laying eggs like crazy!

They also enhance the nutrition for rhinoceros beetle larvae.

When raising rhinoceros beetle larvae, you'll notice a significant increase in size just by burying these in the substrate.

They are also excellent as food for the larvae of stag beetles such as *Dorcus hopei binodulosus*, *Prosopocoilus inclinatus*, *Nipponogomphus viridis*, and *Prosopocoilus giraffa* that feed on mycelium!

They are also suitable for breaking apart to create your own original fermented substrate.

*The photos show one of the items from our inventory.
Please only purchase if you understand that some blocks may be slightly broken or have different shapes.*

This is a limited sale, so the listing will end once sold out.
