The bug Graphosoma italicum striped with warning colours. The bright red and black colouration of this bug makes it deliberately conspicuous to its predators. Warning (aposematic) colouration indicates that the animal so coloured has built-in defences such as poisonous or distasteful flesh or the capacity to strike back in some way. This Graphosoma italicum bug is inedible; its flesh is extremely distasteful to predators. An in- experienced predator will attack and taste this bug, reject its flesh, and be warned in future by the bright colours.
