Enclosure
- Minimum size
- larvae: a container or tub with deep compost or mulch substrate; beetles: approx. 30×30×30 cm
- Substrate
- Larvae: mature leaf compost or white-rot wood, bark mulch and humus-rich soil (30 cm or more deep), evenly damp; do not disturb the self-built pupal cocoon
Feeding
- Food
- Larvae: decaying wood, compost or leaf litter; the beetles barely feed (a little fruit or juice if anything)
- Feeding interval
- the larvae feed continuously from the substrate; keep it damp and top it up
Key facts
- Adult size
- approx. 2.5–4 cm (males up to ~4.7 cm with the horn)
- Life expectancy
- the beetle lives a few weeks to months; larval development takes 3–5 years
- Origin
- Europe, North Africa, western and Central Asia
- Protection status
- SPECIALLY PROTECTED in Germany (Species Protection Ordinance Annex 1, §44 of the Federal Nature Conservation Act): taking it from the wild, buying, selling and possessing wild-taken animals are prohibited. Keeping it is possible only with documented captive-bred animals and proof of origin – ask the authority when in doubt
- Brumation
- The larvae naturally overwinter cool in compost (a univoltine or multi-year cycle); no keeper-controlled brumation of the beetles is needed
- Cohabitation
- The larvae in compost usually get on communally (with plenty of substrate and space); the beetles are short-lived, so pair them for breeding. Note the legal protection status when keeping them singly
Notes
The legal status is the most important point – legal captive-bred animals only. Dose the moisture carefully when watering, as the pupae go mouldy quickly. A common mistake: collecting from the wild (illegal).
