Pammene populana, the pygmy piercer, is a species of moth of the family Tortricidae. It is found in most of Europe, except Portugal, the Balkan Peninsula and Ukraine.[1] The habitat consists of woodland, marshes, riverbanks, fens and sand dunes.[2]
The wingspan is 10–15 mm.[3] Adults have a yellowish blotch on the dorsum with a darker central spot. Meyrick describes it - Forewings dark fuscous, costa posteriorly strigulated with whitish; a triangular ochreous-white median dorsal blotch, apex somewhat bent posteriorly, including a small triangular dark fuscous dorsal spot; three streaks from costa and margins of ocellus leaden-metallic. Hindwings dark fuscous, base lighter. Larva whitish-green; head black; plate of 2 black, anteriorly whitish-green.[4]
They are on wing from July to August.[5]
The larvae feed on Salix species. They spin a shelter from leaf fragments.
