Corythaica bellula Torre-Bueno (Hemiptera: Tingidae): Scribner's Panicgrass, Dichanthelium oligosanthes subsp. Scribnerianum, as a Host Plant in the Nebraska Sandhills
Bibliographic record
Abstract
The lace bug Corythaica bellula Torre-Bueno is one of four North American species in this mainly Neotropical genus. All species known from Canada and the United States are seldom collected and their bionomics little known. Adults and nymphs of C. bellula were collected from Scribner's panicgrass (Dichanthelium oligosanthes subsp. scribnerianum [Nash] Freckmann and Lelong; Poaceae) in 12 counties of the Nebraska Sandhills. Its collection in South Dakota from this host represents a new state record. The panicoid grass is the tingid's second host plant identified to species level. All adult males (n = 51) were brachypterous, as were 90 of 91 females; the single macropter was collected in mid-July. The collection of nymphs in May and July suggests bivoltinism. Nymphs and adults of a congener, C. venusta (Champion), were syntopic with C. bellula at a site in Grant County, Nebraska, which is the first specific locale recorded for C. venusta in the state. Corythaica bellula, whose adults are only 1.98 (brachypters) to 2.20 mm long (macropters), is part of the hidden biodiversity of the vast Nebraska Sandhills.
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.
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; a candidate call from one teacher head, not a consensus.
