Abstract
Abstract. The production and allocation of sperm among successive mates during a male's life largely determine its fitness. The sperm production pattern and sperm allocation to females is studied in Trichogramma evanescens , a short‐lived egg parasitoid of several lepidopteran species. At emergence, virgin males have an average of 1607 ± 249 sperm stored in the seminal vesicles and no further production occurs during adult life. These males are able to mate with at least 20 females in rapid succession. During the first 10 matings, the males transfer approximately 100 sperm each time and then transfer fewer and fewer sperm per mating. The number of sperm stored in spermathecae of successively mated females remains relatively constant for the first 10 females, and decreases slowly for the subsequent females. The relationship between male reproductive strategy and some life‐history traits are discussed.

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
