If you look very closely you can see the inhabitant having a nosey...
Tube web spiders... spin a tubular web, often in cracks of buildings. Six or more silken lines radiate from it, and the spider waits in the entrance, touching the lines with the frontal six legs. Prey triggering these lines get caught, and the spider immediately retreats again to eat it. However, in some cases the spider will kill and begin to consume its prey in the opening of the tube, but will retreat further if disturbed. They hunt nocturnal insects such as moths and cockroaches. Bees and wasps are always bitten at the head end, so the sting will face away from the spider.
The female lays her eggs inside the tube web. Sometimes she will die after the spiderlings have hatched, and they will eat their mother. The spider can be lured to the entrance by gently touching the triplines with a stick in the evening or at night. Wiki.
@maggiemae the inhabitant is a tube web spider...who lurk waiting for their prey to land on the web. The title of the photo was taken from an old tv program "Through the keyhole" and one of the catchphrases is "who lives in a house like this". @lizhammond thank you....I've added a better description above.
