Secret treats to ingest were sent by Count Dracula to Renfield: “Big moths, in the night, with skull and cross-bones on their backs.” The all-knowing Dr Van Helsing explains: “The Acherontia Atropos of the Sphinges, what you call the ‘Death’s-head Moth’?”
Curious eating habits of various kinds had long been observed in asylums, and were discussed by W. C. McIntosh, superintendent of Perth asylum, in 1866:
The morbid desires, longings, or impulses for various substances generally regarded with loathing and disgust have been grouped under the head of Pica.
Although these alien substances were often chalk, charcoal or earth, there is one mention of an insect-eater:
Remaining during winter in a kind of torpid state in the chimney corner, but in summer hunting all day long for honey-bees, humble-bees, and wasps.
While the unfortunate patients may partly have been trying to improve their wretched diets, these days, eating insects is very trendy, and earth will clearly be next.
