Sphinx Moth Pollinations for the Endangered Western Prairie Fringed Orchid, Platanthera Praeclara in Manitoba, Canada
Bibliographic record
Abstract
The western prairie fringed orchid, Platanthera praeclara (Sheviak & Bowles), is an endangered species in North America. In Manitoba orchids produce lower numbers of seed capsules than more southern populations. Exploration of the pollination biology for P. praeclara is critical to preserve this endangered species. This study identified the pollinators of P. praeclara using cone and malaise traps and tested the effectiveness of marking pollinators with traces of Day-Glow® orange marker powder. Although Lepidoptera were numerous in orchid plots during daily observation periods, including day flying Sphingidae, none were pollinators for P. praeclara. Among the 5856 insects from 49 families captured over 45 trapping days, six sphinx moths, two specimens of Hyles gallii (Rottenburg) and four specimens of Sphinx drupiferarum J.E. Smith (Sphingidae), were found with two or more orchid pollinia attached to their eyes and were confirmed as pollinators of P. praeclara. S. drupiferarum is uncommon in southern Manitoba and H. gallii appears to be a less efficient pollinator than S. drupiferarum. Proboscis length, eye width and flight period may influence the efficiency of biotic pollination of the orchid.

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; a candidate call from one teacher head, not a consensus.
