Type locality: [Canada, Alberta] Rocky Mountains. Mamestra curta: syntypes 1 ♁, 1 ♀. [MSU, examined]. Type locality: Colorado. Wilterding (1997) states that there is a holotype, but both specimens are labeled “Type.” Orthosia perpura: holotype ♀. [MSU, examined]. Type locality: Colorado, not New York as stated in Poole (1989). Anarta nivaria: holotype ♁. [BMNH, examined]. Type locality: Colorado Territory. Diagnosis. Lasionycta impingens is a small to medium-sized species (expanse 25– 32 mm) with a gray forewing with orange scales in the medial area and a light yellowbrown hindwing. Th e dorsal hindwing has equally dark discal spot and wide marginal band whereas the marginal band is suffused with the ground color and is more faint than the discal spot on the ventral side. Lasionycta impingens occurs from Yukon to Colorado. It can usually be identified without dissection. Male and female genitalia characters are given in the L. impingens sub-group section. Distribution and biology. Lasionycta impingens occurs from southern Yukon to Colorado. It is diurnal and nocturnal and comes to light. Adults are common in alpine tundra and are often collected by butterfly enthusiasts. It feeds on nectar of a Penstemon species (Scrophulariaceae) on the Beartooth Plateau, Montana, as well as on Mertensia paniculata (Ait.) G. Don (Boraginaceae), and a Senecio, likely S. lugens Richardson (Asteraceae) at Pink Mountain, British Columbia (BC. Schmidt, pers. comm.). Th e moth is found in July and August. Geographical variation. Populations of L. impingens are arranged in two subspecies. Th ere is only slight overlap in the appearance of the subspecies and we considered treating them as species despite absence of structural differences. However, occasional specimens from the range of each taxon are very similar indicating that use of subspecies is appropriate (compare Fig. 102 with Fig. 105 and Fig. 104 with Figs 101 and 103). The CO1 sequences of subspecies L. i. impingens and L. i. curta (Morrison) differ by 0.16 %.

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.
