Make a small groove on the surface and place the larva in it so that it can dig down into the substrate.Fill up the rest of the container with the new substrate (2/3).Place the larva somewhere safe and fill the original container 1/3 of the way up with the old substrate.Do NOT throw away any of the old substrate yet.Tip out the contents of the container including the larva into a bucket.When there are a lot of these faecal pellets in the substrate, it is time to remove some of the old substrate and add in some new substrate, which will be outlined below. With rhino beetle larvae, it is easy to see when the substrate needs changing, as the eaten substrate is excreted in the form of small hard pellets. If the ball of substrate holds its shape and does not drip any water, it is the perfect moisture level. If the ball of substrate does not hold its shape and falls apart when released, the substrate is too dry. If water drips out of the ball when squeezed, the substrate is too wet. The way to check the moisture level of the substrate is to make a ball of substrate in your hand and squeeze hard. Substrate that is too dry will cause larvae to shrivel up from the lack of water and die from moisture loss, whilst substrate that is too wet will encourage the growth of bacteria and fungi that can be harmful to the larvae, as well as allowing the proliferation of mite and small flies. It should be managed carefully to make sure that it does not dry out too much or is not kept too wet. This however means that the control of the moisture level of the substrate is of the utmost importance. Rhino beetle larvae will get all the moisture they require from the substrate they eat so there is no need to spray water daily like when raising other types of insects. Care should also be taken not to add too big of a ventilation hole, or too many holes as this will increase the evaporation rate of water from the substrate which will dry it out quicker. For example, highland species such as Dynastes neptunus and Dynastes satanas should be raised between 15-20C, and lowland species such as Dynastes hercules and Chalcosoma caucasus should be raised between 20-25C.Įnsure that there are several ventilation holes in the lid of the container to allow for the aeration so that the larva doesn’t suffocate. Keep the container in a quiet place out of direct sunlight. The temperature should be controlled according to the needs of the specific species, especially during hot summers or cold winters. As a guide, the minimum volume per larva for average sized rhino beetle species such as Trypoxylus dichotomus should be the following: The container size and volume of substrate should be increased every time the larva sheds into the next L number. So L1 larvae are individuals that have hatched from an egg and have not shed yet, L2 larvae are individuals that have shed once since hatching, and 元 larvae are individuals that have shed twice since hatching. Every time a larva sheds its skin to grow larger, the “L” number increases by one. ![]() Within the larval stage, there are also 3 separate stages called L1, L2 and 元 which essentially stands for “Larval Stage One/Two/Three”. Rhino beetles have 4 distinct developmental stages which are the following: ![]() Details on these substrates can be found in the Beetle Substrate Guide, and my personal recipe for homemade Flake Soil can be found in the Flake Soil Guide. Substrate that can be used for rhino beetle larvae are decayed leaves, white-rot wood, or artificially fermented Flake Soil. ![]() To raise a beetle larva (grub), all you need is a plastic container and suitable substrate.

The larvae feed on decaying wood and leaf litter. The adult beetles feed on a variety of fruits such as banana, apple, pear, peach and watermelon. These are CAPTIVE BRED in my collection, with this stock originating from Chilpancingo city, Guerrero state, Mexico. Their body colour is bright yellow and the thoracic horn of the males have an iridescent, golden undertone when shone under bright light. ![]() This is one of the five species of the smaller, North American group of Hercules Beetles.
