No, it is Egle, Anthomyiidae

I suspected it'd be the female. I saw about a dozen of these flies on the same spot. There where also some Salticus scenicus which caught a few of them. Thanks both!

Jumping spiders catching anthomyiids! I don't recall anyone recording that before. Why not put it into print? |

I'm just a simple amateur photographer and I wouldn't swear that the flies taken by the jumping spiders were Egle ciliata. The jumping spiders were on a blue steel container where the Egle species were sitting in the sun. I assumed they all were the same species. I took a few photos of the spiders with their prey, but if I known it was such a special case I would have concentrated on getting better photos, e.g. I would have gotten a better view of the preys mouthparts. Anyway, here are a couple of photos. The first shows a female prey. |

I have seen Salticidae taking most families of Calyptrate flies (Muscidae, Anthomyiidae, Tachinidae, Sarcophagidae). I think this phenomenon is rather common. (One of my earlier thoughts was that the bristles on Tachinid flies is a means of protecting them from predators, this could still be true, but it will not stop jumping spiders, which regulary target the neck area. I think these spiders jump on everything that moves and is within a certain size range. These Calyptrate families love to take sun at flat surfaces, the ideal hunting ground for Salticid spiders. I have also observed cannibalism, an adult taking another adult of the same species. Bizarrely I have observed Salticid spiders preying on spiders that were much larger than the predator.
