Faunal Composition, Wing Polymorphism and Seasonal Abundance of Some Flea Beetles (Coleoptera: Chrysomelidae) in Southern Quebec (Canada)
Bibliographic record
Abstract
Chrysomelidae (51 taxa) were collected with flight intercept traps from May through October during 1987-1989, in four sites near a raspberry plantation in southern Quebec. More species and individuals of phytophagous flea beetles occurred in two open sites than at a pine woods-raspberry field boundary and in a pine woods. Longitarsus luridus complex, an immigrant taxon in North America, represented 58% of all captures in the two open sites where both Ranunculus acris and Plantago spp. are its main host plants; this species and Longitarsus rubiginosus were almost exclusively represented by jumping apterous adults in pans of flight intercept traps. The seven most abundant chrysomelid species from Johnville are probably all univoltine, and they are apparently not serious raspberry pests. Three life cycle types are apparent: L. luridus complex oviposit in autumn and overwinter as adults. Capraita subvittata, Chaetocnema minuta, Epitrix cucumeris, Phyllotreta striolata and Tricholochmaea alni also overwinter as adults but oviposition begins in spring. Longitarsus rubiginosus oviposits in autumn, overwintering in the egg and/or larval stage.
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.
