Ulex europaeus
The larvae feed on broom ("Cytisus scoparius"), black broom ("Lembotropis nigricans"), aluaga ("Genista scorpius"), dyer's greenweed ("Genista tinctoria"), Spanish broom ("Spartium junceum") and gorse "Ulex europaeus". They create a very untidy, bivalved lobe case of 7–8 mm. The mouth angle is 90°. Full-grown larvae can be found in June.
