Callophrys niphon
species of butterfly

Callophrys niphon, the eastern pine elfin, is a species of Lycaenidae that is native to North America.
Description
It is similar to the western pine elfin but has two dark bars instead of one in the forewing underside cell with strong patterning on the underside. The wingspan ranges from 22–27 mm (0.87–1.06 in).
Life history
There is one flight from March to April in the south, while it occurs between mid-May and early June in the north. Females will lay eggs singly on flower buds. The caterpillars eat both the flower and the developing seedpods. Chrysalids hibernate in loosely formed cocoons beneath litter below the plant. Larval foods include jack pine (Pinus banksiana) and white pine (Pinus strobus).
Range
They range across most of the eastern United States and the southern parts of the provinces of Canada. Within this range they tend to sandy areas with pine trees.
Begin with the source’s own compact description: “Callophrys niphon” is species of butterfly. The dossier treats that line as a proposition to test through Callophrys, niphon 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.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 17, 2022. The linked authority identifier is Q28817385. 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 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.
