Abstract
s from the Fourth International Congress of Dipterology (by J.E. O'Hara) The Fourth International Congress of Dipterology was held in Oxford, England during 6-13 September 1998. A section on the Tachinidae (chaired by myself) was held during the first morning of the Congress, during which five oral presentations were given by four speakers. There were additionally a couple of posters presented at the Congress on the topic of Tachinidae. Abstracts of the oral and poster presentations are provided below. The abstract by Serge Gaponov is included although Serge was unfortunately unable to attend the Congress and consequently did not present his scheduled talk. All of the following abstracts were published in the Abstracts Volume of the Congress, edited by J.W. Ismay. Evolution of Egg Structure in Tachinidae (by S.P. Gaponov) Using a scanning electron microscope I investigated the egg structure of 114 species of Tachinidae. The research was focused on the peculiarities of the egg surface and the structure of the aeropylar area. Data on the method of egg-laying, the structure of the female reproductive system and the host range were also taken into consideration. Since any kind of adaptation is a result of evolution and every stage of ontogenesis, including the egg stage, is adapted to some specific environmental conditions, each stage of ontogenesis evolved more or less independently. The development of provisionary devices (coenogenetic adaptations) and their elaboration was one evolutionary route of ontogenesis in the egg stage of Tachinidae (some groups of macrooviparous and microoviparous species). Another was the shortening and simplification of the stage, leading to the elimination of this phase of ontogenesis (Tachininae, Voriinae, Dexiinae, some groups of Exoristinae). Thus, development of embryonic egg shells as a manifestation of specialised embryo adaptations provides protection and, as a result, stability for the early stages of ontogenesis. Embryonization in the evolution of macrooviparous and microoviparous Tachinidae allows further evolutionary improvement and simplification of those processes of individual development which eventually lead to maturity. Evolution of the egg stage in Tachinidae is caused by phylembryogenesis of which I have observed three modes: anaboly, deviation and reduction through rudimentation. Anaboly consists of the addition of new stages to those which existed in the ancestors; it is conducive to further development of the organs already possessed by the ancestors. Thus, more primitive Diptera have a three-layer chorion in

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.
