Cameraria ohridella was first observed in Macedonia in 1984, and was described as a new species in 1986.
Dispersal of the moth from infested areas occurs on a broad front through adult flight, assisted by the wind, and through the passive transport of adult moths or infested leaves in or on cars and other vehicles. Transportation by vehicles appears to be responsible for the sudden appearance of the moth in towns and cities a long way from known areas of infestation.
Probably aided greatly by this vehicular transport, the moth has attained a very rapid dispersal rate across Europe of 60 km. per year and the species has now been found in Albania, Austria, Belgium, Belarus, Bosnia and Herzegovina, Bulgaria, Croatia, the Czech Republic, Denmark, England and Wales, Finland, France, Germany, Greece, Hungary, Kosovo, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Macedonia, Moldova, Montenegro, the Netherlands, Poland, Serbia, Romania, Russia, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and Ukraine.
The moth is only 5mm long but causes significant damage, mainly late summer browning, to the appearance of horse-chestnut trees (Aesculus hippocastanum). Despite the poor appearance of these infested trees, there is no evidence that damage by the moth leads to tree death. Seed weight and photosynthetic storage and reproductive capacity may however be reduced.
