The status and distribution of Pennington’s Protea butterfly Capys penningtoni (Lepidoptera: Lycaenidae: Theclinae)
Bibliographic record
Abstract
The Red List status of Pennington’s protea butterfly Capys penningtoni has deteriorated from Vulnerable to Critically Endangered since 2009. This species is endemic to part of the midlands and Drakensberg foothills of the province of KwaZulu-Natal, South Africa. Capys penningtoni is restricted to protea savanna where its hostplant, Protea caffra, occurs. A research programme was started when the Red List status of the species was Vulnerable, with the aims of preventing the extinction of C. penningtoni and improving its conservation status. An initial requirement was to more accurately determine the distribution and conservation status of C. penningtoni. A further requirement was to ascertain what might be the main threats facing the species in the wild. Surveillance of the species at some sites was carried out to try and ascertain whether the conservation status of the species was deteriorating further. Our knowledge of the distribution range of the species has improved with the identification of seven previously unknown sites where the species was present. A distribution model was developed for the species that predicted that C. penningtoni could be more widely distributed in the central midlands and Drakensberg foothills of KwaZulu-Natal. The model did not predict the occurrence of the species at three of the newly discovered sites. Further ground-truthing of the model is required. Surveillance results suggest that C. penningtoni may have become locally extinct or less abundant at sites where it was previously recorded, indicating that its conservation status has deteriorated. The main threats to C. penningtoni appears to be the presence of the alien invasive Harlequin ladybird beetle Harmonia axyridis and the inappropriate fire regimes and burning practices in the protea savanna habitat of the species.

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.
