Adscita geryon (Hübner, 1813)
on Helianthemum (Geranium, etc.)
Young larvae make a number of rather large, untidy fleck mines. The opening of the mine is a slit at the side. The mines contain little of no frass. The lower-surface opening, by which the larva has entered the mine, is irregularly roundish. Older larvae live free on the plant.
Helianthemum canum, nummularium.

The description of the mine above is based mainly on Hering (1957a). However, it should be noted that Ebert & Lussi (1994a) do not at all mention a mining behaviour in this species.
