Epermenia aequidentellus (Hofmann, 1867)
Young larvae make several small, full depth blotch mines. They have an opening at the underside, through which most frass is ejected. Mines mostly in the apical part of the composite leaves. Older larvae live externally on the plant under a light web.
Larvae in May – June and August – September (Hering, 1957a).
Not known from the Benelux countries (Fauna Europaea, 2009).
distribution within Europe
From Norway to the Iberian Peninsula, Italy, and Greece, and from Britain to Estonia and Romania; Canary Islands, Madeira (Fauna Europaea, 2009).
Head black; prothoracic shield also, divided by a light line. Body translucent yellow-green with a darker dorsal line and black or brown spots. The black head distinguishes the larvae from those of E. chaerophyllella (Hering, 1957a).
Epermenia daucellus (H de Peyerimhoff, 1870).
In coastal areas, where the leaves of Daucus are more fleshy, the larvae complete their development within the mine (J Langmaid in Godfray & Sterling, 1996a).
