Apterona helicinella (Herrich-Schäffer, 1857)
on various herbs
Case helicoid, about 3 mm in diameter, covered with fine sand grains. The case is distinctly lower than high. From this case fleck mines are eaten in a leaf underside. Contrary to Coleophora species, the case is not anchored to the leaf with spinning. This makes that the cases may drop to the ground upon the slightest touch. Abandoned mines can be recognised because the hole that gave the larva entrance to the mine is not neatly circular and obviously misses the fringe of silken stubbles around the margin.
Larvae in April.
