There are a total of five known species of the genus Eupatorus gracilicornis, all of which are distributed from Yunnan and Guangxi in China to the central and southern parts of the Indochinese Peninsula. Among them, Eupatorus gracilicornis g is the largest in size and the most brightly colored variety.
Chinese name: 五角大兜虫
Latin name: Eupatorus gracilicornis
Alias: Five-horned Rhinoceros Beetle
Kingdom: Animal Kingdom
Genus: Eupatorus sp
Distribution area: Original distribution area is southwestern China, Southeast Asian Peninsula from Yunnan and Guangxi in China to the central and southern parts of the Indochinese Peninsula
The Five-horned Rhinoceros Beetle is the largest family in the genus Eupatorus, with five subspecies. It is also the largest species in the entire genus and has a wide distribution range, from the southwest region of China to the Indochinese Peninsula (Vietnam, Myanmar, Thailand, Malaysia, etc.).
It is recommended to keep the Five-horned Rhinoceros Beetle as a pet for those who enjoy climbing. The breeding and rearing difficulty of the Five-horned Rhinoceros Beetle is average. When setting up the breeding room, it is recommended to mix in rotting leaves or place bamboo leaves, which can help increase the egg-laying capacity of the female beetles. The temperature for rearing the larvae is recommended to be controlled at 25 degrees Celsius. Fermented sawdust can be used as food material, and it is best to mix in some rotting leaves. When the larvae transform into pupae, they have a similar situation to the Horned Rhinoceros Beetle from Southeast Asia, requiring a relatively solid layer of soil.
The environment that should be provided during the dormancy period should be dark, and the container does not need to be too large. Sawdust or sphagnum moss can be used as bedding. Pay attention to maintaining humidity. The depth should be sufficient to completely bury the adult insect in soil or sphagnum moss, so that the adult insect will feel more secure. Place objects such as tree bark on the surface for the adult to turn over. Occasionally, the dormant insect may crawl onto the soil surface. If there is no tree bark for it to turn over, it will inevitably consume energy and may cause death! The temperature should be maintained at 22-28 degrees Celsius, and the higher the temperature, the shorter the dormancy period.
1. Breeding temperature: The varieties of rhinoceros beetles in tropical and subtropical flatlands are bred at a temperature range of 22-26°C, such as the Eupatorus longicorn and Eupatorus porrectus. The varieties in high-altitude areas are bred at a temperature range of 18-22°C, such as the Daimona amplipennis. The unicorn beetles from China to the Korean Peninsula can survive at temperatures ranging from 15-35°C. However, most rhinoceros beetles live longer at an optimal temperature of 20-26°C. After mixing the soil, grab a handful and squeeze. Check if the soil clumps and then disperses when released from the hand.
2. Let's talk about containers: Each type of rhinoceros beetle has a different container size. The container for the large rhinoceros beetles' third instar larvae ranges from 4L to 15L; for the medium-sized rhinoceros beetles, it ranges from 2L to 4L; and for the small rhinoceros beetles, it is 0.5L to 2L. The container needs to be filled with soil and compacted. Regarding the height, especially for the unicorn beetles that pupate vertically, the container height should be more than 10cm.
3. Other equipment, I recommend buying a small electronic scale to record the weight each time the soil is changed. Calipers are used to measure the length of the adult beetles, and you can also buy label cards to record weight in grams.
4. It is not recommended to disturb the pre-pupal and pupal stages of all rhinoceros beetles. If accidentally dug out, buy another flower mud. Vertically pupating beetles, such as the Hercules beetles and unicorn beetles, should be excavated vertically, while horizontally pupating beetles, like the Eupatorus longicorn, should be excavated horizontally. If you want to observe, you can open a skylight, but it should be done when the legs and mouth of the larvae are not moving, otherwise, the larvae will need to remake the pupation chamber. I recommend starting from L1 when raising the larvae. Buy a group (3 or 5) right from the beginning to ensure there are males and females for breeding purposes. Especially for the Eupatorus longicorn, buying a group is cheaper than buying individually.
5. Let's talk about the food for rhinoceros beetles. Unicorn beetles are not picky eaters; they can eat both primary and deep fermented sawdust. The Five-horned Rhinoceros Beetle and South Asian Rhinoceros Beetles are suited for primary fermented bamboo sawdust. It is worth mentioning that the Five-horned Rhinoceros Beetle has a very good effect when fed with fermented bamboo sawdust. Also worth mentioning is that South Asian Rhinoceros Beetles, CM recommends eating deep fermented sawdust. Other rhinoceros beetles can all be fed with deep fermented sawdust. Except for the South Asian Rhinoceros Beetle, other rhinoceros beetles do not eat rotten wood, and even if they do, it is of no use. Nutrient blocks have the same properties as rotten wood, so there is no need to buy them. Nutrient blocks are only meant to deceive novices! So everyone, don't be fooled!
