Conker shortage caused by moth invasion
Well now it seems they have a new enemy. An invasion of foreign moths has hit the conker once again.
The conkers inside are too small and soft to be used in the traditional playground game, which has already been hit by bans around the country because of health and safety fears.
According to the Forestry Commission, the moths are carried by the wind - but can also hitch a lift on cars and lorries.
They first appeared in the UK in Wimbledon in July 2002, when they targeted trees the length and breadth of the southwest London common.
The moth, otherwise known as cameraria ohridella, has now spread across most of south-central England, East Anglia and the Midlands and has been spotted on the Norfolk coast, in Derby, and Cardiff.
Nigel Straw, a scientist with the commission, said: "Infested trees do not look pretty, but they are well able to withstand the damage, and will reflush normally next year.
"At the moment there is nothing we can do to stop the spread in terms of controlling the moth, and we have to live with the damage for now."
The World Conker Championships are taking place in Ashton, Northants, on October 12, and it is feared this new moth infestation will affect them.
Organisers have said that for the first time in the competition's 44-year history, they are worried the shortage of suitably-firm contenders could put its future in jeopardy.
Around 500 people compete in the championships, and right now there are not enough conkers for everyone to compete.
There are fears that the moth could also spread to other trees.
