mined leaves, seen from below
Young larvae live free under the leaves. They bite a hole in the lower epidermis, then graze away as much parenchyma as they can reach from there. The end result is a number of small fleck mines, obviously without frass, and with irregular openings. Large larvae cannot feed in this way.
Cistaceae, Geraniaceae; narrowly polyphagous
Mining larvae in April – May (Hering, 1957a) and October.
