The cover picture shows the ladybird Coccinella septempunctata (Coccinellidae) which, when molested, emits hemolymph droplets at its joints. This mechanism, known as reflex bleeding, constitutes an efficient protection against predators due to the presence of bitter‐tasting alkaloids (e.g. coccinelline). Autogenous production of coccinelline through a fatty acid biosynthetic pathway has been proved. Details on the biosynthetic capabilities of beetles and ants to produce defense compounds are discussed in the microreview by J.‐C. Braekman, D. Daloze et al. on p. 2733 ff.
