Eucosma lacteana (Treitschke, 1835)
feeding trace: silken tube with destroyed flower heads (from Rickert)
The larva lives in a silken tube in the inflorescence, feeding on the capitula and the ripening achenes, all bound together with silk. Pupation in a cocoon among the litter.
In the cecidological literature it is stated that the larva would cause a hard, elongated swelling of the apical part of the main shoot. Probably this is due to confusion with Eucosma metzneriana or E. wimmerana.
Artemisia campestris, maritima.
The association that is mention on Lepiforum with A. absinthium, vulgaris seems dubious.
Univoltine; hibernation as mature larva.
distribution within Europe
Body yellowish to reddish; head dark brown; prothoracic plate light to dark brown, lateral and posterior margin darkly punctuated; pinacula hardly differentiated (Swatschek).
