Bionomics
Oviposition at the leaf underside, mostly in a vein axil.
The larva feeds on Lotus and initially, it makes a long sinuous narrow nepticulid-like gallery with much frass in a broad central line. It ends in an oval blotch, usually near the margin of the leaf which the larva excises for use as its first case.
Later the complete greyish brown case is about 6 mm long. Fully grown larvae in May.
Pupation in the case, usually attached low down on the food plant or nearby vegetation.
The adults rarely come to light.
Flight periods
The adults fly in one generation a year: from late June till early August.
