Many spccics of ladybird bccllcs arc protcctcd against predators by bitter alkaloids present in their h;lcmnlpmph' Till now, the mo?t common of thcsc alkaloids [e.g.prccoccinclIinc (l), cnccincllinc (2), hippodnminc (3) or convcrginc Q] belong to the 2-mcthylpcrhydro-9b-azapt~cncre ring systcm2-.< Other alk;iloids deriving from homotropanchd or pipcridinc7 ring systems have also been dcscribcd, ;ts well as (Z))-

A new dimeric azaphenalene alkaloid, isopsylloborine A (2), has been isolated from the ladybird beetles Halyzia 16-guttata and Vibidia 12-guttata, and its structure determined by 2D NMR methods. It is a double bond isomer of the recently described psylloborine A (1), which is also present in these b
