Wow, this Bug IS a traveler!
I found it during my trip to Brussels. Unfortunately I did not have Internet access there so I could not check the description of its mission and aim. Therefore I ended up moving it the opposite way than it would like to travel. Sorry - I only discovered that when I arrived back at home.
However, I believe that it will like its new temporary home here in the Czech Republic and will get to the UK soon anyway.
Europe is getting smaller and smaller and people tend to travel.
I'm going to send two photos here soon (as soon as I get them out from my camera) - the place where I found it and the place I'm going to put it in.
