The opening Sussex encounter was made by S. J. Patton on 15 September 2004 in Priory Park, Chichester when two larval mines were discovered on London Plane leaves. Single borings were then identified at Fernhurst on 21 August 2005 and 17 June 2007.
The inaugural East Sussex sighting came from P. Bance on 15 August 2006 when 10 caterpillar excavations were found at Scotney (Lamberhurst). A single leaf mine was also seen at Brighton on 25 October 2007.
Little is known about the adult stage, save that it is double-brooded on the continent. (Pratt, 2011)
