Scent glands of male Heliconius erato contain up to 350 components with individual compositions. Linear terpenes dominate, either as esters or as long, regular linear isoprene-oligomers. The high chemical diversity is reflected within the many different mimicry patterns of these butterflies. The compounds were identified by a combination of various methods, including synthesis, which allowed to unravel the underlying biosynthetic pathways used to arrive at these compound bouquets.
