Coleophora adjectella Hering, 1937
from Toll (1962a), after Hering
The first youth case is cut out of an oval mine in the centre of the leaf. The second and third, final, case are excised out of a mine along the leaf margin, and therefore have a serrate dorsal keel. The final case is a spatulate leaf case, laterally strongly compressed, 6-7 mm long, with a bivalved, square-cut rear end. The mouth angle is c. 45°.
Both in his key for Crataegus and Prunus Hering (1957a) writes that the mouth angle is 0°, causing the case to lie flat on the leaf. At the same time he refers to an illustration (practically identical to the one above) that contradicts this.
Larvae from about August till May (Emmet ao, 1996a), but in Denmark the larvae hibernate twice (Buhl ao, 1991a).
Found in Belgium in 2014 (Van Steenwinkel & Wullaert, 2016a).
