ID pointers: A tricky Eupithecia species to identify, especially when worn. Fresh individuals are usually accepted by county moth recorders, even more so if supported with a photograph, but when worn they would require a Gen Det to get accepted. Normally on fresh specimens, the cross-lines preceding and succeeding the discal spot, are acutely angular. There is also a white spot or crest on the back of the thorax. These two features help to separate it from Fletcher’s Pug. The wing tips are more pointed in Larch Pug, more rounded in Grey & Fletcher’s Pug.
