Coleophora conspicuella: case on Centaurea scabiosa

another specimen

Coleophora conspicuella case

from Toll (1952a)

case

A relatively large (12-15 mm), dark brown, lightly curved, somewhat compressed laterally, two-valved sheath case with a narrow ventral keel. Mouth angle 30-45.

hostplants

Asteraceae, oligophagous

Aster amellus; Centaurea aspera, “brachycephalum”, jacea, nigra, scabiosa; Cyanus montanus; Galatella cana, linosyris, sedifolia.

In Britain only on Centaurea nigra. The references to Scabiosa in Hering (1957a), and to Chrysanthemum in Emmet ea (1996a) were mistaken; a reference to Achillea by Patzak (1974a) goes back to a source that cannot be retraced.
