Anyone know of any in the UK
Could it be slugs? I don't know of any insects that specifically eat Japanese knotweed, though some moth caterpillars eat a wide range of plants.
I have been told by CABI UK that there are 2 different ones eating this, a moth larvae and a weevil
Are they something introduced to control it then or have the locals finally decided to eat it?
No they are locals, apparently when their own food source is in short supply they will eat this but only young leaves, its on some spare land near my house and I cut it regular so any leaves are young.
I believe they have introduced something down south that sucks the sap but nothing but natives here
