Londoners are being asked to count all the bees, butterflies and moths they see during Monday as part of what is thought to be first annual city-wide pollinator count.

The project aims to gather more data on the health of all pollinators in the capital.

Pollinating London Together (PLT), a charity focused on making the city a better place for native pollinators, is behind the survey and called the current situation “unsustainable”.

Naturalists, city workers and schoolchildren have been asked to take part in what the charity hopes will “become an annual highlight of the capital’s ecological calendar”.
