Horse chestnut parasite could soon spread to Scotland

Leaf-mining moth, which infects and destroys leaves of 'conker trees', is moving north from England and Wales

Parasitic "hitchhiking" moths, which infect and destroy the leaves of horse chestnut trees, are moving north and could soon invade Scotland.

The horse chestnut leaf-mining moth, which originates in the Balkans, was first recorded in London in 2002 and has spread throughout England and Wales.
