Polystoechotes punctata (Fabricius, 1793) (Neuroptera: Ithonidae) in North America: A Changing Distribution Over Time
Bibliographic record
Abstract
Using label data from 1,448 specimens of the giant lacewing Polystoechotes punctata (Fabricius 1793) (Neuroptera: Ithonidae) representing 849 individual occurrences from North American insect collections, literature, and online sources, we examined capture rates over time, phenology and historic and current distribution for Polystoechotes punctata. Captures spanned 1800 through 2018. They rose between the 1860s to a peak in the 1930s and declined thereafter with an increase since 2000 due to photographs posted online. Captures in the United States and Canada occurred April through November peaking in July and August with 47.6% of the records from August. There are no verified records of P. punctata from east of the Rocky Mountains for over 60 years. The loss rate from eastern North America was not uniform but appears to have occurred in three waves.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
