insect Care Guide & Top Breeds
The overwhelming presence and vitality of beetles and stag beetles
Why Keep insect?
Beetles and stag beetles are loved by a wide range of ages, from children to adults. From Japanese rhinoceros beetles and Dorcus hopei to Hercules beetles and rainbow stag beetles from around the world, there's endless variety to enjoy. Their powerful appearance and unique behaviors captivate passionate collectors.
The joy of insect keeping lies in breeding. Managing adult pairs to spawn, raising larvae in fungal bottles or substrate, and watching them emerge as adults is a special experience of witnessing life's mystery up close. There's enjoyment for everyone from serious breeders aiming for large specimens to families enjoying with children.
Exotic large species require more precise temperature management than domestic species — some need 23-26°C. Many are also sensitive to dryness, making humidity management an important consideration.
Insects require less living space and are relatively inexpensive to keep compared to mammals, making them great pets for city dwellers with limited space.

IntermediateBasic Care Points
Choosing substrate and fungal bottles
For larval rearing, appropriate substrate (fermented or mushroom mat) or fungal bottles are crucial. Fungal bottles are effective for growing large specimens of Dorcus hopei and exotic stag beetles. Fermented substrate is suitable for rhinoceros beetle larvae.
Preparing egg-laying wood and substrate
Stag beetles vary by species — some require egg-laying wood while others lay in substrate. Soak egg-laying wood in water to achieve appropriate moisture before use. Rhinoceros beetles lay in substrate.
Temperature and humidity management
Domestic rhinoceros beetles and stag beetles can be kept at room temperature (20-30°C), but exotic species have different temperature requirements. Hercules beetles need 23-26°C. Regular misting to prevent drying is important.
Avoiding overloading enclosures
Housing multiple adults in the same container causes energy-draining fights between males, shortening lifespans. Even when managing pairs, removing the male after egg-laying extends longevity.
