dutchMost horse chestnuts are infected by leaf miners whose larvae dig into the leaves of the tree and cause small brown patches which spread rapidly across the entire tree. Despite the poor appearance, there is no evidence that this damage by the moth leads to a decline in tree health or tree death.
