Abstract
Abstract Larvae of D endrocerus carpenteri C urtis ( H ymenoptera: M egaspilidae) develop as solitary ectoparasitoids on the prepupae and pupae of primary aphid parasitoids inside the aphid mummy. First instars are aggressive and kill potential competitors; however, facultative gregarious development of two, and occasionally three, larvae may occur under superparasitism. To test the hypothesis that gregarious larvae share host resources equally, adult dry mass is compared between three brood types: ‘double’ mummies containing (i) two males; (ii) two females; or (iii) one male plus one female, respectively. Resource rivalry varies with the sex of the competing larvae. Surviving adults differ significantly in size if both wasps are of the same sex, male or female. A minimum amount of resources is required for a larva to be viable; this threshold does not differ between sexes and is independent of the sex of a competing larva. The outcome of competition between a male larva and a female larva varies with the amount of the available resources, with neither sex being inherently dominant over the other. Females are eight times more likely to be larger than a male competitor if the amount of host resources is ≥0.116 mg, whereas males can win over a female competitor in terms of adult size if the available resources are <0.116 mg. It is suggested that rivalry between larvae for limiting host resources constrains the transition from solitary to gregarious development and should be considered in studies of parasitoid life‐history evolution.

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
