Abstract
The dogbane tiger moth, Cycnia tenera, emits ultrasonic sounds by rhythmically buckling a pair of tymbals when stimulated by pulsed sounds resembling bat echolocation. We monitored the central pattern generator governing this response by recording the motor output of the tymbal branch of the metathoracic leg nerve. The rhythm of the tymbal motor pattern can be altered midway (500 m/sec from its initiation) by changing the period and, to a lesser degree, the intensity of the stimulus. The tymbal response of C. tenera is therefore closed-looped to stimulus pulse period and intensity. Our results suggest that C. tenera relies less on the changes in an attacking bat's echolocation intensity when responding with this behaviour because this acoustic parameter may be a more unreliable indicator of the proximity of the bat than its echolocation call period.

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
