Geographic variation in host selection in the spider wasps <i>Entypus unifasciatus</i> (Say) and <i>Tachypompilus ferrugineus</i> (Say) (Hymenoptera: Pompilidae), II
Bibliographic record
Abstract
This paper is the sequel to a 20 year-long (2002–2021) study of geographic variation in host selection in the common American spider wasps (Hymenoptera: Pompilidae) Entypus unifasciatus (Say) (Pepsini) and Tachypompilus ferrugineus (Say) (Pompilini) (rusty spider wasp). Geography and host spider family are strongly linked in both species when 3387 host spider locality records from the years 1918–2021 are mapped. Entypus unifasciatus lycosid host records are plentiful from 43–44° N in the United States and southern Ontario to northern Mexico. Tachypompilus ferrugineus lycosid host records are abundant from southern Ontario and New England southward to Mexico east of the Rocky Mountains. The vast majority (~80%) of E. unifasciatus and T. ferrugineus pisaurid host records are from the southeastern United States. Trechaleid host records for E. unifasciatus and T. ferrugineus are predominant in southern Mexico and Central America, while ctenid host records for these spider wasps are prevalent in Central America and, especially, South America. All E. unifasciatus sparassid host records are from extreme southwestern United States and northern Mexico, whereas T. ferrugineus sparassid host records are scattered from Texas, Florida and Hispaniola/Puerto Rico southward to Panama and Brazil. Based on this study Lycosidae is the predominant host spider family in the Americas for E. unifasciatus (83.1%) and T. ferrugineus (64.0%) followed by Pisauridae (4.9%, 24.8%), Trechaleidae (4.2%, 6.0%), Ctenidae (4.3%, 2.7%), and Sparassidae (3.1%, 1.6%). Lycosidae and Pisauridae are overrepresented in this study as most host records (88.1%) are from the United States and Ontario, Canada where such species are abundant. Trechaleidae and Ctenidae are grossly underrepresented as host records from Mexico, Central America and South America are scarce (11.9%). Zoropsidae/Miturgidae 2 · March 31, 2022 Kurczewski et al. and Zoropsidae/Agelenidae/Selenopidae are atypical host spider families for E. unifasciatus (0.2%, 0.2%) and T. ferrugineus (0.7%, 0.2%, <0.1%), respectively. Rabidosa rabida (Walckenaer) (Lycosidae) (rabid wolf spider) is the predominant host spider species for both E. unifasciatus (47.7%) and T. ferrugineus (48.0%) based mainly on United States host records.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
