Abstract
3.1.2.1.Andrena(Micrandrena)alfkenellaPerkins, 1914 Figures 17 B, F, 21 C Andrena alfkenella Perkins, 1914: 112–113, ♀ ♂ [England: NHMUK or OUMNH]. Andrena moricella Perkins, 1914: 113, ♂ [England: NHMUK or OUMNH]. Andrena alfkenella ssp. sunna Warncke, 1975 b: 295, ♀ ♂ [Spain: OLML]. Distribution and habitat. Mostly mesic habitats in Morocco, Europe and the northwestern Middle East. In the Levant, limited to mountains above 1300 m in north and central Lebanon (Wood et al. 2020). Flight period. Late April at least until mid-July (in Europe until August), in two generations. Flower preferences. Polylectic. Pollen hosts include Apiaceae, Brassicaceae, Plantaginaceae and Rosaceae (Westrich 1989). The second generation exhibits strong preference for Apiaceae pollen (TJW, unpublished data). IUCN (2024) also mentions foraging on Asteraceae, Boraginaceae and Campanulaceae. In Lebanon, recorded on Chaerophyllum, Euphorbia and Peltaria (Wood et al. 2020). Material examined.

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.
