Cameraria ohridella winning the war

[knocker]

The UK’s conker trees are under threat because native insects are losing the war against an alien invader.

 

In less than three decades the horse chestnut leaf-mining moth, Cameraria ohridella, has spread from Greece to almost the whole of Europe, arriving on these shores around 10 years ago.

 

The moth, which burrows through the leaves of conker trees causing them to turn brown and die, was first spotted in south London in 2002 and can now be seen across almost the whole of England and Wales.
