Eupithecia linariata, the toadflax pug, is a moth of the family Geometridae. The species can be found in Europe and from Anatolia to Tajikistan and Iran. The wingspan is 11–16 mm. The moth flies from April to October depending on the location. There is one generation per year. It is very similar to the more common foxglove pug but flies earlier in the year, has a much darker (often almost black) abdomen band, a sharper angled outer edge to the dark forewing band, and is cleaner and often brighter looking in colouration.
