Stephensia cedronellae (Walsingham, 1908)
Bystropogon plumosus & Cedronella canariensis; from Hering (1927a)
Narrow gallery, often following the leaf margin for some distance, ending in a large full depth blotch. Some silk is layed in the blotch, causing it to pucker slightly. In the corridor the frass is in a central line, in the blotch as scattered grains. In large leaves the larva may change mine.
Larvae from January till March (Hering, 1957a).
