Ethmia aurifluella (Hübner, 1810)
on Anchusa, Onosma
From a silken tube in the heart of the plant the larva tunnels in the stem to the root collar, that is eaten out so thoroughly that the plant dies. All frass is accumulated in the opper end of the gallery.
Experimentally the larvae developed well on Echium vulgare.
Univoltine; hibernation as pupa.
