case

A straw-coloured, slender, three-valved case of he type “tubular silken case”; length about 10 mm, mouth angle 45° – 60°. Larve at the leaf underside. Perhaps because of the plant’s dense felt cover, the case is attached with much silk, giving the openings a conspicuous white margin.

host plants

Asteraceae, narrowly oligophagous

Achillea millefolium; Artemisia absinthium, vulgaris; Carduus; Inula; Leucanthemum vulgare; Tanacetum corymbosum, vulgare.

Because in the past the interpretation of this species has long been uncertain, references of food plants from that time are unreliable. References to Hieracium need confirmation.
