Hexarthrius parryi
A large two-pronged stag beetle distributed in India, Myanmar, Thailand, and nearby areas. Features long bifurcated mandibles and is one of the largest species in its genus. The body luster and mandible shape are highly valued by enthusiasts.
Hexarthrius parryi is a large fork-jawed stag beetle distributed across India, Myanmar, and Thailand. Its long, forked mandibles are its hallmark, and it is known to grow particularly large within the genus. The glossy body and mandible shape are admired by enthusiasts. Husbandry uses a small to medium enclosure with oviposition logs and fermented substrate. Adults are fed insect jelly, and larvae reared in fungal substrate bottles can yield large individuals. Because the mandibles are long and powerful, careful handling is needed. Combining presence and beauty, it is popular in breeding.

Breeding notes
Females lay eggs in fermented wood or substrate; hatched larvae are reared in fermented mat or fungal (mycelium) bottles. After eclosion, adults require several months of dormancy before they are ready to breed.
Breeding requires planning, proper husbandry, and responsibility. These figures are general guidelines.

Popular species that grows particularly large among two-pronged types
Keep at 20-27°C. Avoid extreme heat or cold and hold a stable temperature year-round.
Set up a small to medium case with a breeding log and fermented substrate. The long, strong mandibles can pinch, so handle with care.
Feed adults beetle jelly. Raising larvae in kinshi bottles lets you aim for large individuals.
Laying in a breeding log is the norm. Bury the log in substrate and split it once the larvae have grown somewhat.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Parryi Stag Beetle is 20〜27℃. Avoid sudden temperature changes and maintain a stable environment.
