Glow-worms could be lighting up South Downs National Park, after being introduced to a new site there. The common glow-worm has struggled in the UK because of artificial lighting and habitat loss, and are now classified as near threatened. Conservationists are hoping that by creating a new home on the dark sky reserve, the species can flourish. The larvae have come from Devon and are expected to grow into adults by next summer, when we might catch glimpses of the glowing displays.
