Chrysomelina
Chrysomelina is a subtribe of leaf beetles within the family Chrysomelidae, subfamily Chrysomelinae. Members of this subtribe are characterized by their ability to produce chemical defenses, including de novo synthesis of iridoids (cyclic monoterpenes) and host-plant-dependent compounds such as salicylaldehyde. Larvae possess specialized glandular secretions used to repel predators. The subtribe exhibits diverse defensive strategies that have evolved through recruitment of oxidases from the glucose-methanol-choline (GMC) oxidoreductase superfamily. Some species display subsocial behavior with maternal care of offspring.
