“ If the caterpillar were large it would be terrible, for it protects itself, being soft-skinned and often helpless, by a mimicry of rage, pawing the ground, lashing its head furiously from one side to another, as a lion lashes its tail, rearing itself up menacingly in a sphinx-like attitude, grinding its mandibles with a grating sound. Its color is at first usually green like the leaf it feeds on, but it afterwards develops bright hues in some species. The Troilus caterpillar is green with a yellow stripe on each side, and row of blue dots, while its under side and feet are reddish. ”
