Labrynth Spider (Agelena labyrinthica)

Yet it was a particularly valuable friend to 16th Century Austrian Monks.
Why?
Head for this video (and commentary) to find out:

Notoriously so!
It was basically a lot of patience, sitting perfectly still (not easy on a windy day, reflected in the video) and getting that zoom head on to the tunnel without causing a shadow, because that seemed to trigger a scuttle back into the safety of the labyrinth.
