People in a 14th floor office, drinking rubbish coffee
Three beetles (possibly Salpingidae, narrow-waisted bark beetles) found huddled together under a flake of bark on a pine tree, by a student in 9SH. Body 8mm long, tarsal formula 5-5-4, wing cases with rows of little puncture holes.
This is as close as I can get without going out of focus. Here's hoping its close enough but eben if it't not I've now learned its a beard lichen, so thanks :-)
Lichen on the trunk of a live tree.
Was in a small flock of about 5 - 8 birds
