The ornate moth Utethesia ornatrix produces (i )-(-)-hydroxydanaidal (Figure 10.4) from pyrrolizidine alkaloids like monocrotaline N-oxide, and uses it as a sex attractant for females as the danaid butterflies do. The aphid Aphis jacobaeae also feeds on Senecio plants and stores these alkaloids. The ladybird Coccinella septempunctata (Plate 3) feeding on the aphids accumulates the pyrrolizidine alkaloids in turn, but does not accumulate cardiac glycosides (see earlier).
