First pictures of the Horse Chestnut miner (Cameraria ohridella).
This was found for the first time last year (2002) in a South London suburb (Wimbledon). It was first found in 1985 near Lake Ohrid in Macedonia. It has since spread extremely rapidly through Europe.
It even has it's own web site: http://www.cameraria.de/cameraria_e.html
|The mines are very distinctive and one side of the leaf is 'blistered'
as shown here. Take care that you do not confuse this mine with the
fungus which affects Horse Chestnut - the areas affected are red also, but with
a yellow edge.
During 2003 the miner has spread through South London and the mines shown were collected on 15th October 2003 by Colin Plant and Rachel Terry in Greenford, Middlesex. It has also been discovered in North Oxford in 2003. It has also spread to Tonbridge, Kent, where mines were reported by Keith Palmer on 18th September.
It is expected to spread rapidly in this country - certainly a miner to look out for.

|Martin Honey discovered this leaf miner in the grounds of
the Natural History Museum last year (2002) feeding on Quercus ilex (Evergreen Oak).
John Langmaid has collected these mines and Ian Thirlwell has photographed them:
It is found in several localities in Greater London.
Martin Honey would be very interested to see if it occurs elsewhere in the UK and to track its spread in Britain.
Its Bradley number will be 36a.
