Abstract
Abstract Our objective was to test the hypothesis that late-instar nymph, male, and (or) female German cockroaches, Blattella germanica (L.), use sonic signals for intraspecific communication. A digital-recording system was assembled that consisted of a computer equipped with data-acquisition hardware and software, microphones sensitive to sonic and ultrasonic frequencies, and speakers capable of emitting sonic and ultrasonic sound. Sound was repeatedly recorded from groups of five nymphs, five virgin males, or five virgin females. Click-type sounds were commonly present in recordings from nymphs, and consisted of sound pulses of about 10-ms duration and peak frequencies of 7, 9, 11, and 14 kHz. Similar "clicks" were found in recordings from females. In replicated binary choice arena bioassays with individual laboratory-reared insects, played-back "clicks" from nymphs or females or computer-generated artificial clicks attracted nymphs but not males or females. These results provide the first evidence that sonic signals are part of the complex B . germanica communication system.

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 it
