Plant Parasites of Europe

leafminers, galls and fungi

Eucosma lacteana

Eucosma lacteana (Treitschke, 1835)

maritime bell

on Artemisa

Eucosma lacteana: feeding trace

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.

host plants

Asteraceae, monophagous

Artemisia campestris, maritima.

The association that is mention on Lepiforum with A. absinthium, vulgaris seems dubious.


Univoltine; hibernation as mature larva.

Body yellowish to reddish; head dark brown; prothoracic plate light to dark brown, lateral and posterior margin darkly punctuated; pinacula hardly differentiated (Swatschek).
