Oh? I have an interest in entomology, and when they mix it with symbolism - it's even better. You think you could recommend me any other thing to read with particular topic?
To go a bit further back into the nineteenth century, Edgar Allan Poe has a splendid little short story called "The Sphinx" that you might find of interest.
Later on, of course, there's Stoker's
Dracula. The character Renfield ingests insects in hopes of altering his being (consumption => metamorphosis => Kafka). There's also something insect-like, bat-like, and reptilian about Dracula himself.
Philip K. Dick has some very explicit references to insects in his short stories from the fifties, specifically "The Father-Thing" (in which metallic insect-like creatures masquerade as humans) and "The Hanging Stranger" (which features insect-like things from an alternative dimension; they even have "stingers"
).
More recently, China Miéville employs insect imagery for several of the characters in his
Bas-Lag trilogy (there's a certain race of beings that have human bodies and insect heads, with "mandibles," as I recall).
I'm mostly interested in insect imagery as it relates to a culturally normative sense of animal hierarchy. When we anthropomorphize dogs, for instance, we tend to see them positively, or as figures of "good"; insects, on the other hand, often exude malice and conjure up dread in characters. Their relationship to our concept of "the other" is very interesting.
