A ladybird's color indicates how well-fed and how toxic it is, according to scientists. This research directly shows that differences between animals' warning signals reveal how poisonous individuals are to predators. The study shows that redder ladybirds are more poisonous than their paler peers and reveals that this variation is directly linked to diet in early life, with better-fed ladybirds being more visible and more deadly.
