Coleophora bilineella, case on Cistus creticus

Often a new leaf segment is attached to the old one under an angle. The oldest parts of the case then loose their function, and the oral opening of the new section is reused as the anal one.

case

Laterally adpressed, composite leaf case, built of 2-4 leaf fragments of different age (colour). Case small, < 10 mm, bivalved, mouth angle 45°. The youth case is excised out of a blotch mine, mostly at the leaf margin. Fleck mines hypophyllous.

host plants

Cistaceae, oligophagous

Cistus creticus, monspeliensis, salviifolius; Fumana; Helianthemum canum, hirtum.
