Caterpillars is a short story by Edward Frederic Benson about a man haunted by dreams of enormous caterpillars.
In the beautiful Villa Cascana on the Italian Riviera, all is not as it seems. Why does the hostess leave a perfectly charming bedroom unoccupied? Why does Arthur Inglis present our hero with a caterpillar in a cardboard pill-box one lunchtime? And rather more bizarrely, why do luminous, bloated and gigantic versions of this creature haunt his dreams? Or could it possibly be that he is wide awake?
