Derelict enough?

I think this may be my first venture into monochrome since the inception of digital photography and my joining of Blip; I just thought it went correctly with the dereliction.
The extra - for Clicky. There was one of last year's which must have overwintered in the half-formed tadpole with legs stage, but it shot under a cobble too fast; this one's a guessimetric 2" / 5cm long.
