A few weeks ago I spotted one of these 'shapes' on the floor and saw it move and just suspected the wind. Two days ago I spotted another moving and on closer examination came to the conclusion it was an ant pulling it along.
Tonight I saw one hanging on the wall moving again, put my strong glasses on, got a surprise and then gave myself a right work-up persuading it to become a photographic subject. I have not got a clue what it is and I'm pretty certain at one time I saw a head emerge from both ends !
The body or should I say housing is 8mm long.
Comments and suggestions welcome as always.
