For several years each November I've checked the fallen London Plane leaves on the road-side at Salterhebble sewage works for the mines of Phyllonorycter platani in the belief that one day they would turn up and today was my lucky day.
I believe it may be a first for Calderdale but the species is spreading slowly northwards and is expected to become more widespread.
One to look out for!
From Yorkshire moth website.....
First found in Britain in the London area in 1990, this plane mining species has since spread at a steady pace. The first Yorkshire county records were from adjacent localities in York (VC62 and 61) in 2007 with further records from Hull (VC61) in 2008 and from Doncaster (VC63) in 2009. Likely to be found more widely in the future, mainly in suburban or parkland areas where the host tree has been planted.
