According to a study from Jena, Germany, "The larval defenses of chrysomeline leaf beetles comprise components that are either synthesized de novo or sequestered from their food plants. Both biosynthetic modes are based on glucosides that serve as substrates and forms of transport."
"The defensive glands import the compounds through highly selective glucoside transporters from a circulating pool in the hemolymph. Here we address the selectivity of the different transport systems with larvae of Chrysomela populi, an obligate sequestering species, and with larvae of Phaedon cochleariae, producing nonaterpene iridoids. Both species possess an interconnected network ...
