The broom seed beetle, Bruchidius villosus (L.)
Introduced for biocontrol of broom, Cystisus scoparius, adult beetles are commonly found inside broom flowers. Females lay pale coloured, elongate eggs singly on the outside of green seed pods, and a single larva develops inside an individual seed. Adult beetles escape from dry, blackened pods when they dehisce in summer. This beetle also develops on tree lucerne (tagasaste) (Chamaecytisus palmensis or Cytisus proliferus). By Pauline Syrett.
