Скачать или смотреть Ensign Fly (Sepsidae sp) - Brighton, November 2021

I previously featured one of the few Ensign flies found in the UK which can be relatively easily identified by a clear photograph, here:    • Ensign Fly (Nemopoda nitidula) - Brighton,...  

Also called Black Scavenger flies, or Ant-mimicking flies, both videos demonstrate how much they resemble tiny winged ants, black, with relatively large, rounded heads, often glossy, and sometimes with silvery hairs on the thorax.

Unlike Nemopoda nitidula, this specimen carries the clear black spot on the wings characteristic of many species in this family.

It also has a visible green sheen on the rear half of each wing, which I first thought was a reflection of light off the leaf surface.

However, I can find no references to such a characteristic, in any species descriptions, so I cannot use it to try to identify the specific species, in the film.

Although both of these videos show a lone specimen, Ensign flies are often found in swarms.
