Phaulernis dentella (also known as the scale-tooth lance-wing) is a moth of the family Epermeniidae found in Asia and Europe. The moth was first described by Philipp Christoph Zeller in 1839.
The wingspan is 9–10 mm. The forewings are blackish-brown, with a scattering of white scales and there is a distinct tuft on the dorsum.[1] There is one generation per year with adults on wing in June and can occasionally be seen on the flowers of the larval foodplant.[2] [3]
The larvae feed on the seeds of burnet-saxifrage (Pimpinella saxifraga), bulbous chervil (Chaerophyllum bulbosum), rough chervil (Chaerophyllum temulum), ground elder (Aegopodium podagraria), hogweed (Heracleum sphondylium) and wild angelica (Angelica sylvestris).[4] Larvae can be found from July and August.[3] [1]
It is found in central and eastern Europe, the Caucasus and western Siberia.[5]
