Horse Chestnut Leaf Miner
Following concerns expressed about this pest I am able to provide the following information, courtesy of the Woodland Trust:-
Horse Chestnut Leaf Miner, an invasive moth affecting horse chestnut trees. This tree pest has been present in the UK since 2002, having been introduced into Wimbledon from the continent. The pest has spread quite rapidly and has now reached its northern limit in southern Scotland.
Its larvae (caterpillars) mine within the leaves, and at high population densities they can destroy most of the leaf tissues. Although it can cause severe damage to horse chestnut leaves on an annual basis, and discolouration and defoliation before normal autumn leaf-fall, on its own the pest does not significantly impair trees’ health, and they will usually flush normally the following spring. The trees at the original outbreak site in Wimbledon have since recovered this is due, in part, to blue tits and other birds removing larvae from the leaves.
Damage can be reduced by removing fallen leaves during the autumn and winter and either composting them thoroughly, to destroy the over-wintering pupae, or if the leaves are collected into smaller heaps, by covering them with a layer of soil or other plant material to prevent adult emergence the following spring.
