§1 Foulness, Essex; 24/05/2009; male; fw 3.8mm
§2 Foulden Common, Norfolk; 14/08/2006; male; fw 2.9mm - THIRD FOR NORFOLK
Ben and I also obtained this species at Foulden on 23/05/2016. The identification was confirmed by gen.det. but, having previously processed the August specimen presented above, I did not retain any images of the May specimen - this is unfortunate because the May specimen turns out to have been the FIRST FOR NORFOLK
