Melanchra assimilis Black Arches
Bibliographic record
Abstract
18. Melanchra assimilis (Morrison) Black Arches (Fig. 34, Map 19) Identification: Forewing length 15–17 mm. This is a dark gray moth with black markings and a white angular spot at the juncture of the outer and posterior margins of the forewings. The black markings include an orbicular spot, claviform spot, an incomplete antemedial line extending from the claviform to posterior margin, forming a short scalloped line, a reniform spot, and a very fine curved, scalloped postmedial line. The subterminal line consists of three obscure white dots bordered by a few black scales in apical half of forewing, a variable amount of white scales (sometimes mostly absent) leading to the angular white spot at the tornus. Hindwing is white with a gray discal spot and a wide gray marginal band that can vary in intensity. Flight period: Mid-August in the Park. Collected localities: North Carolina: Haywood Co., Purchase Knob at house. (1 specimen) Elevation range: 4924 ft. (1501m) General distribution: This is a boreal species that is distributed across Canada from Nova Scotia to British Columbia and in the United States from Maine south to western Maryland and in Great Smoky Mountains National Park in Hayward Co., North Carolina. It is also distributed in the upper Midwest from northern Ohio west to North Dakota. Larval hosts: This species is a fairly polyphagous, mainly feeding on low forest plants and occasionally invading forest trees as a solitary defoliatior (Prentice 1962). Hosts include goldenrod (Solidago sp., Asteraceae) (Goodell 1881); brake fern (Pteris sp., Pteridaceae) (Dyar 1904); bracken and other low plants (Forbes 1954); willow (Salix sp., Salicaceae) (Crumb 1956); buffalo berry (Shepherdia sp., Elaeagnaceae), alder (Alnus sp., Betulaceae), European white birch (Betula pendula Roth, Betulaceae), white ash (Fraxinus americana L., Oleaceae) (Prentice 1962); and cinnamon fern (Osmunda cinnamomea L., Osmundaceae), gray birch (Betula populifolia Marsh., Betulaceae), birch (Betula sp., Betulaceae) (Godfrey 1972). The larva is illustrated in Wagner (2005). MAP 19. Collecting localities of Melanchra assimillis.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
