Conservationists call for help to save London’s glowworms

London Wildlife Trust asks volunteers to seek out endangered beetles' strongholds

They were celebrated as ye country comets" by the poet Andrew Marvell but glowworms are defying light pollution to still shine their lights in the city of London.

Now volunteers and enthusiasts are being sought to count and save the much-celebrated but declining beetles, whose females emit a remarkable bright green bioluminescent beam to attract males.
