The first observation of this xerothermic species in Belgium was on 08 July 2006 in the province of WV.
During 2007 there were about 10 different observations in 5 new localities. Around 2010 more and more observations in our country became known.
The species is extending its range northwards, especially in the western part (France, Switzerland) and is recently discovered in the UK (2002), Germany (2002) and in The Netherlands (2006). During autumn 2005 there were several observations not far (35 km) from the Belgian border in France.
