Life history traits and interactions of <i>Stylops advarians</i> (Strepsiptera) with its bee host, <i>Andrena milwaukeensis</i>
Bibliographic record
Abstract
Specimens of Stylops advarians were sampled by collecting foraging bees of Andrena milwaukeensis along the South Saskatchewan River within Saskatoon, Saskatchewan. As the foraging season progressed from early May till late June over three consecutive years (2016-2018), most stylopized bees possessed endoparasitic adult (neotenic) females of S. advarians protruding from the bee gaster's dorsum. In contrast, very few adult bees stylopized by male puparia, and no free-living males, were encountered. Over the sampling period, prevalence remained around 22% each year; mean intensity was 1.2 (range of 1-3 female parasites per bee); and parasite abundance was 0.27. Also newly reported for Stylops is the occurrence of one bee bearing four Stylops (two neotenic females and two males with puparia), plus another bee with a male puparium extruded from its gaster's sternites. Around 2 May each year, a high proportion of the earliest captured female bees were stylopized. However, non-stylopized female bees typically were not encountered until about 10 days later, suggesting the parasites manipulate female bee hosts to emerge earlier, in close synchrony to male bee emergence. First-instar larvae of S. advarians appeared from 22-25 May, indicating that adults of S. advarians matured and mated at similar times each season.

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.
