Acer platanoides
As well as colonising the leaves of the common horse-chestnut, "C. ohridella" is also able to feed on "Aesculus pavia", "Acer platanoides" and "Acer pseudoplatanus", on which in particular one mitochondrial race, haplotype B, seems to develop successfully when nearby horse-chestnut leaves are exhausted, but is not thought to pose such a strong risk to these species unlike to the common horse-chestnut.
