The first eastern North American records for the introduced European rhyparochromids <i>Drymus brunneus</i> (Sahlberg) and <i>Raglius alboacuminatus</i> (Goeze), and an additional record of <i>Gastrodes grossipes</i> (DeGeer) in North America
Bibliographic record
Abstract
the European rhyparochromid species Raglius alboacuminatus (Goeze) and Drymus brunneus (Sahlberg) have both been introduced into western north America, where they are now established in several states and provinces.A third European rhyparochromid species, Gastrodes grossipes (deGeer), was previously intercepted in shipments from Europe to Ontario, and was not previously thought to have been established in north America.Based on collections in southern Ontario, we here report D. brunneus and R. alboacuminatus as established in eastern north America; G. grossipes is recorded for the second time in Canada but is not yet known to be established.the known natural history of the three species is briefly reviewed.Material examined includes specimens from the following collections: university of Guelph Insect Collection, Guelph, Ontario (dEBu); Canadian Centre for dnA Barcoding, Guelph, Ontario (CCdB); and the Canadian national Collection of Insects, Ottawa, Ontario (CnCI). Drymus brunneus (sahlberg) (fig. 1)Drymus brunneus was originally recorded in north America from British Columbia by Scudder and Foottit (2006), and had not been recorded elsewhere in north America until specimens were found in Ontario. the presence of D. brunneus in Ontario was originally based on collections and observations from 2017 to 2019 by SPL in a suburban woodlot in Richmond Hill.Individuals were found by roughly shaking leaf litter (to dislodge any insects within the sample) over a small container and were found largely associated with alder

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; both teacher heads agree on what is shown here.
