Botanophila seneciella
species of insect
Botanophila seneciella, the ragwort seed fly or ragwort seed head fly, is a fly species in the family Anthomyiidae.
Larvae feed within seed heads of Jacobaea vulgaris (the tansy ragwort), often destroying all of the developing seeds. It is also found feeding on Senecio vulgaris (the groundsel).
These flies originated in France. Together with the cinnabar moth (Tyria jacobaeae) and the tansy ragwort flea beetle (Longitarsus jacobaeae), the ragwort seed fly can be used for the biological control of the tansy ragwort. It has been approved and released for Senecio control in California, Australia and elsewhere.
Begin with the source’s own compact description: “Botanophila seneciella” is species of insect. The dossier treats that line as a proposition to test through Botanophila, seneciella and species, not as a finished interpretation.
Why this record matters
The phrase “species of insect” 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 Mar 13, 2026. The linked authority identifier is Q14221306. None of the 0 selected statements returned an explicit reference.
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.
