Psocoptera (Barkfly) query

Looking through old images and came across these two tiny little flies (2-3mm long). With the wings so much longer than the abdomen I think they are Barkflies or Psocoptera species.

This image was taken in May 2016, and looks very similar to Ectopsocus briggsi. If correct, there are no current records on Aderyn for East Glamorgan.

The other was seen in July 2016 but I'm not sure on this one. There appear to be several with similar wing venation.

Has anybody else seen/recorded any of these little beasties?


  1. Hi Howard, I've been recording these on and off for a year or so after discovering the excellent online key on the barkfly recording scheme website. By strange coincidence I saw E briggsi for the first time this morning, in my moth trap left overnight in a Fairwater churchyard.

    I'm not familiar with the other species with those strikingly long antennae.

    1. Hi George.
      Looking back at my notes, both were attracted to the Moth Box light - one was in the box and the other, E Brigsii, was photographed where it sat on a window frame.
      Comparison of the wing venation with with on-line images suggests Psococerastis gibbosa for our friend with the long antenna and you can just make out a similar head/face pattern from my first (poor) image as well. So if I had to put a name to it that's what I'd go for!
