Conker shortage caused by moth invasion

As mchawk reported at the end of August, the beloved British Chestnut trees are under attack from a fungus. 

Well now it seems they have a new enemy. An invasion of foreign moths has hit the conker once again.

The moth, called Leaf Miner Larvae, from Greece and Macedonia, have been attacking the leaves and nuts and causing them to turn brown and fall off before they are fully developed.

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.

amyjudd, I like this story. It's good stuff.


I think these moths are doing the rounds in France as well.  I was in Paris two weeks ago and the trees there had leaf-blight.  It doesn't bode well for this peculiar British sport.

These magnificent Horse Chestnut Trees in Ruskin Park, London seem to have avoided this blight this year. It would be very unfortunate if they were attacked in years to come as they are such a impressive sight right in the middle of the park.

Ruskin Park is our local park. Visit our site at http://www.loughboroughjunction.com

This is the first year my trees have borne fruit. There they are- by the hundreds.

A recent windstorm, spawned by hurricane Ike, knocked down a rather large number of trees in our area. The weight of the nuts made me think my American Chestnuts would have a hard go of it in the windstorm. Though they were severely stressed, they came through unscathed.

Has this moth spread to Ireland yet?

This photo was taken for an assignment in our local photo club for the topic autumn. It is a studio shot lit by a wireless flash. More description about the setup can be found under the link.

Thanks for using my image and making me aware of this site. These are beautiful magastic trees and grow to huge proportions, it would be a shame to lose them . I hope a solution is found, i'm all in favour of let nature run its course but not destructively.

It's an important story, but a couple of errors (OK, I'm a pedant!):

It's the Horse Chestnut that is affected, not the Chestnut (an entirely different tree!).

The moth is not called "Leaf Miner Larvae" - that's a generic description of the caterpillars of  many types of moth that live between the leaf cuticles, eating tracks across them. The common name is Horse Chestnut Leaf Miner, but Cameraria ohridella is what it should be called...

It's amazing how fast the moth spreads. The first year they appeared in Morden Hall Park, every leaf seemed to have turned brown by August. I thought about calculating the numbers of caterpillars involved, but it was too scary...

I am fortunate to live on an Island off the NW coast of Scotland. Here we escaped Dutch Elm disease and hopefully we will escape this current infestation and our most colourful autumn trees will be safe. Our trees have to stand against extreme weather conditions - and I am constantly adding to my own collection of trees on my land. Let us hope that as weather conditions seem to be getting more erratic, my little contribution will survive and thrive for the wildlife around me.

I took this photo over a year ago when I first noticed a problem. This year the trees have been attacked again, but this time to a much greater degree.

Lots of trees on the Isle of Wight, UK have this infection - it is a real shame to see such beautiful trees dying.

I have always loved conkers, I think it is something to do with the rich colours, I still can't walk pass a newly fallen concker without picking it up and admire it's natural beauty.

This tree still looks healthy to me in 2008. But having grown out of the conker stage (aged 70+) I don't know the conker situation.

I live in Hungary and the leaf miner does not seem to have had any affect on the conker crop here.  I have never seen so many conkers- you walk down the street and conkers are dropping off the trees all over.

Although it didn't look too bad when I took the photo, there are now a lot of brown leaves on the trees.

These photos were taken on the Long Walk in Windsor UK a long avenue with chestnut trees lining both sides. Visited recently and it's once again full of conkers. Didn't notice anything odd about them, but on my way to work riding through Virginia Water there are many smaller conkers lying on the ground.

Our nearest big Horse Chestnut (where I got the conkers in picture to make crochet copies of) is on a roundabout. I must brave the traffic and see how it's faring!

I have to confess to having been a huge conker fan when I was a wee young lad at school, especially enjoying all the rumours of how to make you're conker the haerdest, many a country walk would end in climbing trees and throwing up sticks to knock down the largest conkers to then scuttle home and bake, store in airing cupoard, soak in vinigaer and all the other "tricks" to try and have the champion conker that season. Nothing beat putting a washer under the conker just above the know on teh string to spread the load more..aahhh the joys of dads getting involved and making it technical!

Thanks for using the photo, the conkers are from Clifton, Bristol collected a few weeks ago.

The conkers seem to be doing ok in West London. I collected mine within short walk of my house, though I have noticed more blemishes on them that I've seen in the past.

These conkers were gathered from trees which I've been told are suffering from an infestation of the moth larvae. The conkers seem much the same as normal, but the leaves on the trees turned brown prematurely.

Not only in GB or Greece, even here in Japan. May have to make more sick. Be interesting to find out, it should be possible to make silk from the Moth Worm, may not be the same quality though.

I took this picture as part of a project for a photogrpahy night class. Glad it was of help. I have just read the story in the paper, it is a real shame because they are beautiful things conkers.

Conkers remind us all of our childhood. It would be a dreadful shame not to see them in their full splendour. They are part of our British Autumn.
