Abstract
Scaeva (Scaeva) pyrastri (Linnaeus, 1758) Musca pyrastri Linnaeus, 1758: 594. Type locality: Sweden (Svecia). Musca rosae De Geer, 1776: 108. Unjustified new name for Musca pyrastri Linnaeus. Musca mellina Harris, 1780: 30. Type locality: England. Scaeva corrusca Gravenhorst, 1807: 375. Type locality: Germany (not given). Scaeva affinis Say, 1823: 93. Type locality: USA (Arkansas). Scaeva unicolor Curtis, 1834: 509. Type locality: Great Britain (England: the neighborhood of London). Syrphus pyrastri var. flavoscutellatus Girschner, 1884: 197. Type locality: Germany (Thüringen). World distribution: NE: Canada, USA. OR: India, Pakistan. PA: Afghanistan, Algeria, Canary Is., China, Egypt, Europe (widespread), Madeira, Mongolia. Egyptian localities: Eastern Desert: Wadi Rishrash [Shaumar & Kamal (1978)]. Activity period in Egypt: March. Remarks: This is a highly mobile species, usually exploiting concentrations of aphids wherever it finds them. Adults are fast fliers, usually within 3m of the ground; they are frequently encountered flying around bushes and shrubs in a slow and purposeful manner, only to speed away after 30 seconds or so. It is to a significant extent anthropophilic, occurring in arable crops, hedgerows, orchards, gardens and conifer plantations. In Europe, it has been recorded visiting an extensive list of flowers, especially the Umbelliferae (De Buck 1990; Speight 2017). In Egypt the larvae were seen feeding ravenously on aphids (Efflatoun 1922).

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
