Begin with the source’s own compact description: “Galeruca tanaceti” is species of leaf beetle. The dossier treats that line as a proposition to test through Galeruca, tanaceti and species, not as a finished interpretation.
Why this record matters
The phrase “species of leaf beetle” 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.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Nov 5, 2025. The linked authority identifier is Q1307197. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1758.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
