Information reviewed17 July 2026
Dorcus parallelipipedus is a European stag beetle of white-rotted broad-leaved wood. The larva develops slowly inside a stump, log or dead section of a living tree, pupates there and may remain inside as a newly formed adult through winter.

Europe and western AsiaBroad documented range and representative regional anchors — not a complete occurrence map.
Woodland, parks, hedgerows and gardens where decaying broad-leaved stumps, logs and standing dead wood remain.
Adults are most active in warm months, often at dusk or at night, and may come to light.
Larvae consume fungus-softened decaying wood; adults take sap and soft fruit.
Solitary, although several larvae and adults may occupy the same decaying stump.
What makes this species remarkable?
The larval stage usually takes two to three years, with development speed strongly affected by temperature and the season in which the egg was laid.
Pupation occurs inside the same decaying wood, and the newly formed adult may overwinter sealed in its pupal chamber before emerging.
A single retained stump or dead section of a living tree can support repeated generations without the beetle attacking healthy wood.
