Pteronarcys californica Newport 1848
Bibliographic record
Abstract
Pteronarcys californica Newport, 1848 http://lsid.speciesfile.org/urn:lsid: Plecoptera.speciesfile.org: TaxonName:470665 (Figs. 18–23) Remarks and Distribution. Previous larval descriptions and illustrations are available for this species (Smith 1917, Claassen 1931, McCafferty 1981). It can be separated from larvae of other Pteronarcys based on the absence of lateral abdominal projections (Figs. 18, 23), welldeveloped, acutely pointed pronotal projections (Figs. 20, 23), pointed triangular wing pads (Figs. 21, 23), and a pointed, semi-lunate, conical supraantennal process (Figs. 19, 22). This widespread and often abundant species is distributed throughout the Canadian Rockies from Alaska south to Arizona and west to the Coastal Ranges of far western North America (Jewett 1959, Baumann et al. 1977, Stewart & Oswood 2006). Material Examined. Canada, British Columbia: Summerland, 12 May 1959, ♀, Exv, R.E. Leech (CNC); USA, Colorado: Larimer Co., Big Thompson River, Viestenz Smith Park, 9 June 2005, ♀, 3 Exv, R.

Kondratieff (CSUIC); Grand Co., Colorado River, US 40 below Byers Canyon, 4L, 28 April 2010, B. Heinold (CSUIC); Oregon: Clackamas Co., Salmon River, submerged wood, 1 mi.

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.
