Me and my wife moved in to a new flat in June this year. Not too long after we started seeing this centipede in various locations around the flat. They appear about once or twice a month and they tend to sit quite high up on the wall, always on their own and the don't move much, so it's hard to tell where they come from or where they go. It's almost like when we're out one just runs out from their hiding and sits there waiting for me to come home and get rid of it. The frequency of them appearing hasn't increased nor decreased.
Anyway, we'd like to know what it is. Haven't managed to find anything looking like it on the internet.
Think one would measure about 3cm if it was straight, but normally, unlike the picture I attached, they are curled up in a spiral shape.
Hopefully one of our entom specialists will get back to you soon via Nature Plus, but if you are planning a trip to visit us at the museum in London anytime soon you could always bring it along to the Angela Marmont Centre for identifcation:
It belongs to the order Geophilomorpha which, according to http://www.bmig.org.uk/index.php?q=btaxa, have 32 species in Britain. These are in general impossible to identify from photos as the differences are on a microscopical level. They are predators, completely harmless (except for their prey) and live on things that might be less harmless. I've had some of those fellas living in my flower pots (many species are common in greenhouses).
