Europe's largest stag beetle. Lucanus cervus is famous as Europe's iconic beetle.
Lucanus cervus, the European stag beetle, is the largest stag beetle in Europe, distributed from the British Isles through central and southern Europe to Asia Minor. They inhabit deciduous forests, particularly those with old oak trees, where larvae spend 3–5 years feeding in decaying roots—a feature that makes captive rearing quite challenging. A well-ventilated enclosure with broadleaf hardwood logs is required for egg-laying. Adults live only 1–3 months. The species is legally protected in several European countries and is recognized as a flagship species for woodland conservation. Its iconic status in European natural history and the challenge of multi-year larval rearing make it a prestigious species among stag beetle enthusiasts worldwide.
The Lucanus Stag Beetle lives Adult 1-3 months.
The Lucanus Stag Beetle grows to 30-85mm.
Males bear impressively large, branched mandibles resembling a stag's antlers, reaching 30–85 mm in body length with a reddish-brown to dark brown coloration.
Cool temperature management at 18–22°C is essential.

May be protected in Europe. Check regulations
Keep in a well-ventilated case. Mimic a rotten hardwood environment such as oak, and avoid stuffiness and heat.
Feed adults beetle jelly. Larvae grow by eating decayed hardwood roots and rotten wood, so keep wood available.
Use rotten hardwood such as oak for egg laying. The larval stage is very long at 3-5 years, and the difficulty is high.
Adults live only 1-3 months. Once you have adults, set up for egg laying promptly while keeping them cool.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
The average lifespan of Lucanus Stag Beetle is Adult 1-3 months. With proper care and nutrition, they can live a long and healthy life.
Lucanus Stag Beetle typically reaches 30-85mm as an adult. Size may vary depending on care conditions and individual genetics.
Lucanus Stag Beetle feeds on: Insect jelly. Aim for a balanced diet with appropriate feeding frequency.
