Pieris marginalis
species of butterfly
Pieris marginalis (margined white) is a butterfly species seen across the coast of Western North America. It is a canopy generalist who feeds on the plant family of Brassiceae. The species is unique as it has been seen near and away from disturbed habitat; indicating an adaptation for habitat generalization.
Description
The summer form is purely white, while the spring form has black-tipped upper forewing. The underside of hindwing and the apex of forewing have veins edged with yellow-green or gray-green. The wingspan ranges from 1 1/2 to 2 1/4 inches (3.8 to 5.7 centimeters).
Begin with the source’s own compact description: “Pieris marginalis” is species of butterfly. The dossier treats that line as a proposition to test through Pieris, marginalis and species, not as a finished interpretation.
Why this record matters
The phrase “species of butterfly” 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.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Mar 8, 2026. The linked authority identifier is Q2234814. 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.
