The four-spotted footman is a moth with no permanent populations in the Netherlands. It is a rare migratory moth, entering the Netherlands from the south and possibly temporarily propagates. This year the moth is reported strikingly more than usually.
The four-spotted footman (Lithosia quadra) was from 2004 to 2013 reported only thirty times and thus a rare moth. In normal years, zero to four individuals were reported. In good years there were seven (2006) to nine (2012) four-spotted footmen. Only in 2014, over a hundred reports came in on Waarneming.nl and Telmee, from more than fifty different locations. The past week still saw a lot.
