![]() ![]() 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. Beetle Egg Laying Guide Trypoxylus dichotomus larvae on Flake Soil This is part 1, of a four part care sheet that covers the breeding of beetles:Ĥ. Insects with complete metamorphosis include beetles, bees, ants, butterflies, moths, fleas, and mosquitoes.How to Care for Beetle Larvae (Care Sheet) Once the adult leaves the pupa it slowly stretches out and relaxes under the sun for a couple of hours while its exoskeleton dries out and hardens. Inside the pupa, the larva’s body will completely change into a fully grown adult. The pupa appears lifeless, but one of Nature’s most amazing transformations is happening. At this stage the larva will stop eating and moving. The number of instar stages can be different depending on the type of insect.Īt the end of the larval stage the insect will make a hard shell and inside it will become a pupa. For example, instead of being called a baby, a very young larva would be called an instar 1 and a teenager would be called an instar 3. Scientists refer to these developmental changes as instars which are similar to how humans call their children babies, toddlers, or teenagers. Some larvae add more body segments as they grow. For insects, this super-sized larva diet makes them grow very fast. ![]() If humans did the same thing, babies would start out eating as much as 10 pounds of food each day. Larvae have a very big appetite and can eat several times their own body weight every day. Complete metamorphosis begins with the insect hatching from an egg into a soft worm-like shape called a larva. ![]()
