Nasty little creatures, most caterpillars are. And arrogant, no less. The more colourful they are, the more poisonous and unpalateable. The vivid colours are usually their way of saying, as Sheldon puts it, neener-neener.
They also have an insatiable appetite. Eating many times their weight, a single caterpillar can devour most of the young leaves and shoots on a bush, like this one was in the process of doing.
