Female glow worm (Lampyris noctiluca) on scrubby heathland border. Arne, Dorset, UK.
Apparently they were clearing up after a theatre show last night at Durlston and 3 glow worms were spotted just behind the visitor centre in the long grass.
Funnily enough I saw 2 at Durlston tonight in the car park as I prepared to leave!
