About Eupithecia succenturiata (Linnaeus, 1758)
This species is easily recognizable, primarily because of its color combination and large size compared to most other pugs. Its wingspan ranges from 21 to 24 mm. Typically, this moth has whitish forewings with broad dark grey margins, or brown-suffused margins. It is highly variable, however, and individuals can be nearly all white or nearly all grey. There is a small dark discal spot on the forewings. The hindwings share a similar coloration and also have a small discal spot. The abdomen has a conspicuous pattern: it is grey with a white base. The larva is light brown, with numerous small white warts scattered across its entire body. It bears a narrow white lateral stripe and a series of diamond-shaped brown spots along its back.
