Chestnut Leaf Miner

[Bill Thomson]

Am I right in noticing that the chestnut leaf miner has almost disappeared this year?

Last year there were less than in earlier years so Horse Chestnut leaves lasted longer. This year I’ve caught a few moths in my traps but a fraction of 2-3 years ago.  Last year we blamed the wet weather but that’s not the case this year.  I’m in Surrey maybe just a local effect. Interested to hear others experience.

Last year I noticed the same thing here in south west France, after years of it getting worse and earlier, there was very little sign.

 

Some trees this year seem free so far, others less so.

Yes . Now you mention it ...

Is it not still a bit early for them though ?

[Khriss]

Nope. Seeing a lot around here in SE. Bit later but possibly the hot spell delayed them?  K

to be fair haven't noticed this year yet. Usually have seen it a bit later on in Summer.

Not noticed a lot around the North West and Midlands personally, I hope this will be the trend.

You might be right but there are several generations of them starting about April. There have been less so far but I suppose it’s not too late for them to really get going.

For the first week in August, that’s not bad.

 

I have seen some completely brown, others not so bad compared to previous years.

Yes hasn’t been hammering as much so far
