Abstract
Abstract Mate acquiring activities often expose males to increased risks of predation. In species where females are more competitive than males (i.e. a reversal in the conventional mating roles), the mate-acquiring biology of females is expected to increase their exposure to predators. Our observational study of a role-reversed dance fly, Rhamphomyia longicauda Loew (Empididae), supports this prediction. Within predominantly female swarms, R. longicauda display structures in flight that are assessed by males. Structural and behavioural components of the display should increase the risk of predation on females. We found more females than males captured in spider webs. This bias in predation was not due to a female-bias in population sex-ratios of the dance fly and the nature of web predation appears to rule out the hypothesis that spiders actively favour females as prey.

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 it
