Abstract
Two spotted stink bug Perillus bioculatus (Fabricius 1775) is a North American species known as an efficient predator on the Colorado potato beetle (Leptinotarsa decemlineata Say).On the North American continent it is common in Canada, Mexico and the United States of America and has two or three generations per year.In the USA he met almost the entire territory, with the exception of the south-east.In Canada P. bioculatus controls density population of the phytophage in the southern parts of the country.In Mexico the predator P. bioculatus has been registered in many areas (Henry & Froeschner, 1988; Maw et al., 2000).The nymphs are round to oval in shape.There are five instars.The body length of the four instars averages 1-1,5; 2-3; 4-5 and 6-7 mm, respectively.Mature nymphs of the two spotted stink bug are about 8 to 9 mm long.Adults range in length from 8,5 to 11,5 mm.This species has a different color forms -from white and black to red and black (with various intermediate yellow and black forms) with a distinct black "Yshaped" marking on the pronotum and two black spots on the thorax.P. bioculatus overwinters under plant debris around the margins of potato fields in adult stage.This species has been mass-reared for biological control of the Colorado potato beetle.It is known, that an average of 1.5 individuals (nymphs of the later instars or adults) P. bioculatus per plant reduce the number of Colorado potato beetle population to zero in seven days (Ferro, 1994).For this reason, in the second half of the 20th century two spotted stink bug P. bioculatus was introduced into Europe in order to restrain the Colorado potato beetle.However, numerous attempts of the entomologists at acclimatization of the P.bioculatus in Europe were not successful.The first information about registration of the two spotted stink bug on the European continent came in 2004, when he was found in the European part of Turkey (Kivan, 2004).Later it was found in other countries: Russia -in Crimean, Seversk, Slavyansk, Dinsk and Krasnoarmeysk districts of the Krasnodar region, Aksai district of the Rostov region, in

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.
