Phora Latreille View in CoL (total of 70 photos of 44 mating events examined: Figure 4E–F View Figure 4 )

Phora is the genus for which we found the most photos on iNaturalist, probably because of the size and conspicuousness of these phorids. Phora males are larger than the females and have a group of setulae on the posterior face of the hind femur and a highly variable hypopygia with developed surstyli. The photos examined show a standard mating position ( Figure 4E–F View Figure 4 ). A video posted by one of us (BVB) shows a Phora pair mating (https:// 10.5281/zenodo.14625309). The video starts with the male and female already in copula and the male performing rhythmic up-and-down movements of his hind femora which seem to be rubbing the female terminalia. As in Dohrniphora , the base of the posterior face of the male hind femur is the region in apparent contact with the female terminalia. This phase lasts for at least 25 seconds (captured by the video). After this, there is a short stop phase in which the male is motionless, followed by a few up-down movements of the male hind leg and detachment from the female. The female does not seem to make clear rejection movements in the video. In spite of the male hind femur’s possible role of female stimulation, this structure is not variable within the genus, contrasting with the case of Dohrniphora .
