Habroloma geranii (Silfverberg, 1977)
Upper-surface or full depth blotch, that begins in a leaf segment and extends towards the centre of the leaf. Oviposition usually in the upper side of a thick vein. The female covers the oviposition site with a drop of brownish-black secretion that hardens while drying, and is not washed away by rain. The dry drop does not shine, unlike in Trachys species. Pupation in the mine.
Geraniaceae, narrowly monophagous
Larvae from end June – end July.
BE recorded Bilý (2002a; Fauna Europea, 2007).
NE recorded (Brechtel & Kostenbader, 2002a); this is not confirmed by the Fauna Europaea (2007), given the hostplant probably correctly.
LUX not recorded (Fauna Europaea, 2007).
distribution within Europe
All of Europe, except Ireland and the Balkan Peninsula (Fauna Europaea, 2007).
The larva has a big black spot on most segments; see Schaefer (1949a) and Bilý (1982a, 1993a, 1994a) for a description, Brechtel & Kostenbader (2002a) and Niehuis (2004a) for a picture.
Habroloma nana (Paykull, 1799).
The hostplant in Germany is species of dry, hot slopes; in the Netherlands it is an ornamental, that rarely escapes.
