Leaf detritus beneath all the horse chestnut trees I have recorded in Sturovo and Esztergom are home to a huge population of overwintering pupa of the Cameraria Ohridella moth – a species first observed in the late 1970s in the Macedonia region and which has since made steady progress north and west throughout Europe. It arrived in Slovakia in 1994 near the border with Austria (ref. Matlak 1994). These photographs are taken in my studio in Sturovo, using a microscope connected to a lap top.
