Food Plant: Aesculus hippocastanum (Horse Chestnut), Sycamore (Acer pseudoplatanus), Norway maple (Acer platanoides).

Mine: Multivolitine, with up to three generations a year. May - October

Notes: First discovered in Macedonia in 1985, it has rapidly spread across Europe and is gaining a rapid foothold in the UK, since its discovery in 2002. There can be many mines on a leaf and the miner can cause serious defoliation. It is occasionally found mining Norway Maple (as shown), particularly in heavy infestations. (Note also the two Stigmella aceris mines either side of the petiole).

Data: 10.ix.2006, Fleet, Hants, VC12
