# Click here for a list of stag beetle and rhinoceros beetle products on Mercari! For single rearing of Japanese rhinoceros beetle larvae Nutritious This is an offering of "1500ml tall clear bottles ☆ Himalayan Hiratake fermented mat". Japanese rhinoceros beetle larvae create pupal chambers vertically, so we created a dedicated tall bottle. With a clear bottle, you can clearly see inside, and we will ship it with a carefully selected bottle that allows you to clearly observe the larvae, pupae, and emergence, filled with nutritious fermented mat. You can raise the rhinoceros beetle larvae just by putting them in this bottle. It has ventilation holes and a special filter to prevent the entry of small flies. Quantity: Set of 12 You can add as many as you like. We will ship the number you want. You can easily observe the growth and feeding traces of the larvae with the high-performance clear bottle. This is a carefully selected bottle that won't break even if dropped. From years of research, we have finished a new, top-quality mycelial fermentation mat made from 100% Japanese oak sawdust, the most effective for Japanese rhinoceros beetles, called "Himalayan Hiratake," and it is in the bottle. Nutritional supplements that help the larvae grow larger are also included. Furthermore, symbiotic bacteria are also blended in. By adding bacteria, the symbiotic microorganisms in the digestive tract that break down cellulose, which is a source of protein, become active, and the absorption rate of nutrients improves. Giving it from a young age leads to size increase. In experiments, larvae raised with premium fermented mats containing abundant symbiotic microorganisms such as internal bacteria have grown much larger than those raised with commercially available mats. We do not use any "waste mycelium" discarded by mushroom growers, but instead, we crush new mycelium made from oak sawdust and ferment it slowly for a long time in a controlled room. It contains the ultimate, carefully selected mat that has been completed with a long time and high cost. Most general fermented mats from other companies use waste mycelium discarded by mushroom growers as raw materials, and their nutritional value is also reduced. Also, inexpensive mats are fermented outdoors, so there are many cases where miscellaneous insects and fly eggs are mixed in, and miscellaneous insects appear during breeding. Our "Himalayan Hiratake Fermented Mat" is made by slowly fermenting only new mycelium in a controlled room, so there is no 100% chance of miscellaneous insects being mixed in, and miscellaneous insects and small flies will not appear during breeding. The bottle lid has a special filter to prevent small flies from entering from the outside. Many Japanese rhinoceros beetles have emerged at 88mm.
