Leucoptera orobi (Stainton, 1869)
The mines begins as a spirally gallery; this is overrun by a later blotch, that may occupy the entire leaflet. Frass initially in the centre of the blotch, later more dispersed.
Fabaceae, narrowly monophagous
Reports on literature of Lathyrus tuberosus are due probably to an incorrect interpretation of Orobus tuberosus (= L. montanus) (Emnmet, 1985a).
Maček (1999a) reports orobi from Slovenia on Lathyrus laevigatus; that not only is a new hostplant, but also far removed from its known distributional area.
Larvae in July, a small number also in September (Emmet, 1985a).
Not known from the Benelux countries (Fauna Europaea, 2009).
distribution within Europe
Fennoscandia, British Isles (Fauna Europaea, 2009).
Leucoptera orobi and L. lathyrifoliella are very closely related, and some authors consider them synonymous; see Kaila & Wikström (2004a).
