Eucosma lacteana (Treitschke, 1835)
maritime bell
on Artemisa
feeding trace: silken tube with destroyed flower heads (from Rickert)
larva
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.
phenology
Univoltine; hibernation as mature larva.
distribution within Europe
larva
Body yellowish to reddish; head dark brown; prothoracic plate light to dark brown, lateral and posterior margin darkly punctuated; pinacula hardly differentiated (Swatschek).
pupa
