Dibolia femoralis Redtenbacher, 1849
Large, brown, opaque blotches in the lower leaves, mostly radiating from the leaf tip. Frass, concentrated in the centre of the mine, visible from below as black patches. Pupation outside the mine (Doguet, 1994a; Hering, 1957a). Mines cannot be distinguished from those of D. schillingi on the same host plant, but the adults of femoralis have thoracic shield punctated much more finely.hostplants
Salvia austriaca, barrelieri, nemorosa, pratensis.
S. pratensis is the main hostplant (Doguet, 1994a; Hering, 1957a).
Larvae in May-June; hibernation als imago; univoltine (Doguet, 1994a). According to Hering (1957a) larvae are found in two generations, April-June, then again in August.
Not known (Fauna Europaea, 2007).
distribution within Europe
France Germany – Poland – Ukraine, and all of Europe further to the south (Doguet, 1994a; Fauna Europaea, 2007).
Larvae yellowish brown, communal; they are able to leave their mine and restart elsewhere (Hering, 1924a). Steinhausen (1994a) gives a key to the larvae – as far as these are known.
