Abstract
Thereva duplicis Coquillett Specimens examined (0). Database and literature records (13). BC: Fort St. John; Quesnel; Soda Creek. YT: Minto Landing. CASC, SEM. Conservation status. BC: S3S4, YT: SU Distributional notes. Only three localities are known in British Columbia for T. duplicis, two in the Cariboo (Quesnel, Soda Creek) and one in the Peace River region (Fort St. John). Probably the species ranges extensively in the North, based on records in the Yukon, Northwest Territories, and Alberta (Webb et al. 2013). Thereva duplicis is mostly a species of the Great Plains but extends west into the Cordillera and east in the boreal forest as far as Ontario. There is one record in the central Yukon (Minto Landing). Ecoprovinces and other designations. BC: Central Interior, Boreal Plains. YT: Boreal Cordillera. Range. Great Plains. Yukon and Northwest Territories east to Ontario, south to Michigan, Minnesota, South Dakota, Wyoming, and Montana (Webb et al. 2013). Biological notes. Flight period: 25 June–29 July. Thereva duplicis mainly lives in mixed or broadleaf woodland (Holston & Irwin 2005) but also has been recorded in boreal forest and prairie habitats.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
