Stenoptilia lutescens (Herrich-Schäffer, 1855)
The biology of the larvae is unknown; possibly the larvae develop in the flowers.
Gentianaceae, narrowly monophagous
distribution within Europe
See Nel; pictures on Lepiforum.
The status of Stenoptilia arvernica (Peyerimhoff, 1875) is not clear; it might be a (junior) synonym of lutescens. The species would live on G. burseri, lutea and G. lutescens.
