Beautiful engraving of the Migratory Locust (Pachytylus migratorius) - 'Locusts assemble together and migrate from place to place in vast swarms - this habit really constituting almost the only difference between locusts and many other grasshoppers. Locusts leave scarcely anything in the nature of vegetation untouched, when, as often happens, they invade a district where the ordinary herbs and grasses are insufficient to support their vast numbers. Trees and shrubs are then stripped bare of their leaves, and the bark and wood even are not spared. Pressed by hunger, locusts do not refrain from attacking plants which at ordinary times they seem to avoid. They frequently devour their own dead, and even carry their cannibalism so far as to kill and eat the newly-moulted and soft skinned larvae' (1894)
