Cytisus scoparius
The larvae feed on "Ulex europaeus", "Cytisus scoparius", "Cytisus nigricans", "Genista germanica", "Lupinus arboreus" and "Calicotome spinosa". On "Ulex" and "Cytisus scoparius", they make a small hole in a bud that is not fully open and feed on the interior of the flower, before repeating the process in another flower. On "Lupinus arboreus", the larvae feed on the leaves instead of the flowers. Larvae can be found from April to early May. Pupation takes place on the ground in a slight cocoon amongst leaves.
