Goliath Beetle

Goliath Beetles are native to Thailand, Indonesia, and Malaysia. They can grow up to 6-13 cm in size, making them the largest members of their family. They have metallic green elytra and two horn-like protrusions on their thorax. They thrive in temperatures ranging from

Goliath Beetles are nocturnal beetles and have a strong phototactic behavior. They live for about 1.5-2 years in their larval stage, going through three molts before pupating. The first instar larval stage takes about 30-40 days, the second instar stage takes 30-40 days, and the third instar stage takes 1-1.5 years. The adult beetles only live for about 4-6 months. The larvae mainly feed on decaying leaf litter and require high-protein food to grow into the largest adults. The adults primarily feed on ripe fruits such as bananas, apples, and honey, although commercially available pre-packaged food is also convenient.

Goliath Beetle is the smallest and most easily distinguishable subspecies native to Thailand, Indonesia, and Malaysia. It is also the easiest subspecies to breed. The male beetle can grow up to 60-120 mm in length (wild individuals are likely even larger), while the female beetle reaches 50-65 mm.

It is recommended to keep Goliath Beetles as pets for those who enjoy climbing insects. Generally speaking, as long as the stable breeding environment is maintained, it is not difficult to breed Goliath Beetles. The joy of successful breeding is also an incomparable enjoyment.

The environment that should be given during hibernation period, darkness, the container does not need to be too large, wood chips or sphagnum moss as bedding, pay attention to maintaining humidity, the depth should be sufficient to completely bury the adult into the soil or sphagnum moss, so that the adult will feel more secure, place objects such as tree bark on the surface for the adult to turn over, occasionally the dormant insect may also crawl to the surface, if there is no tree bark for it to turn over, it will inevitably consume energy and may cause death! Keep the temperature in an environment of 22~28 degrees, the higher the temperature, the shorter the hibernation period.

Breeding method for larvae: It is generally best to have a relative space of 4-5 liters or more for each larva. Separate rearing: Each larva is reared in a separate container, which requires a large space, but it can increase the chances of breeding large individuals. The disadvantage is that independent rearing can cause the male and female larvae to have different moulting times, which affects pairing.

Improvement methods: 1. When changing the soil each time, the remaining old soil in each box can be mixed with new soil and allocated to each rearing box. 2. During the mid-stage of the third instar, mixed rearing can be done, but the weight of male and female individuals may decrease due to mixed rearing, but the difference won't be significant. Mixed rearing: Although it doesn't take up much space, the male and female individuals bred through this method will have significant differences in body size, but the difference in moulting time won't be long, and the larval period will be shorter than separate rearing.

Larval period: It varies from about 14 months to 26 months. Larval food: A mixture of rotting wood and fermented wood shavings in a ratio of 1:1. The humidity can be slightly higher than for breeding, and a few pieces of wood can be added. Generally, most Goliath Beetles are artificially bred, so it is necessary to pay attention to whether the adult beetles have passed the dormant period before mating.

If the adult beetles have passed the dormant period, they will almost start eating. You can use the touch method to see if the adults make any threatening movements and whether their claws have a strong grip. If so, it means that the adult beetles have passed the dormant period and can be mated. Breeding supplies: Rearing box (large organizing box), rotting wood and leaf soil mixture, adult climbing tree bark or wood pieces, etc.
