Dorcus parallelipipedus
species of beetles

Dorcus parallelipipedus, the lesser stag beetle, is a species of stag beetle found in Europe.
Description
Both sexes resemble the female greater stag beetle (Lucanus cervus), though they are a uniformly blackish colour rather than having the chestnut brown wing covers (elytra) of the larger species. Males have distinctly knobbed antennae, and although their jaws are somewhat larger than those of the females, they are nowhere near as large as those of many other male stag beetles. The lesser stag beetle is similar in appearance to the related antelope beetle (Dorcus parallelus) of North America. Adults are from 18 to 32 mm (0.7 to 1.3 in) in length.
Diet
Like those of other stag beetles, the white, C-shaped larvae feed on wood. Adults as well as larvae are found in very soft decaying wood of broad-leaved trees, especially ash (Fraxinus excelsior), beech (Fagus sylvatica) and apple (Malus spp). Adults cannot eat solid food, but they can drink tree sap and the liquid of fallen fruits.
Life cycle and habitat
Adult beetles can be found in woodland, parkland and hedgerows in the summer, often resting in the sun on trees. After they mate, females lay their eggs in rotting, decaying wood.
Begin with the source’s own compact description: “Dorcus parallelipipedus” is species of beetles. The dossier treats that line as a proposition to test through Dorcus, parallelipipedus and species, not as a finished interpretation.
Why this record matters
The phrase “species of beetles” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jan 24, 2026. The linked authority identifier is Q805094. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
