Abstract
Abstract While the diversity of most taxa increases from temperate to tropical regions, the parasitoid wasp family Ichneumonidae has often been cited as an example of an anomalous diversity pattern with their highest diversity at mid‐latitudes. A rich body of literature has attempted to explain this pattern and provide hypothesised mechanisms, and recent studies have suggested that the pattern may result from biases in the data. Previous studies of patterns in ichneumonid diversity have mined catalogue data or have compared collections from tropical and temperate areas across a limited range of latitudes. Few studies are available that include species richness for all subfamilies, and none have been from regions above 60°N. To increase the number of datasets available to address these patterns, we first tested the assumption that subfamily abundance can be a strong predictor of species richness. We then compared abundances of ichneumonid subfamilies in field collections from a wide range of latitudes (25°S–81°N), and used generalised additive models to evaluate characteristics of the subfamilies as predictors of the observed patterns. We demonstrate a wide variety of latitudinal patterns, reflecting the ecological variation between subfamilies. In addition, our models show that host taxon and subfamily identities are better predictors of the shape of the relationship between subfamily abundance and latitude than other characteristics that have been previously hypothesised to be important, including parasitoid life history strategy and body size.

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
