Insectoids in science fiction and fantasy

Occasionally, an earth-bound setting — such as in the film The Fly (1958), in which a scientist is accidentally transformed into a grotesque human–fly hybrid, or Kafka's famous novella The Metamorphosis (1915), which does not bother to explain how a man becomes an enormous insect — is the venue.

[3] Notable later depictions of hostile insect aliens include the antagonistic "Arachnids", or "Bugs", in Robert A. Heinlein's novel Starship Troopers (1959)[4] and the "buggers" in Orson Scott Card's Ender's Game series (from 1985).

[7] Insectoid sexuality has been addressed in Philip Jose Farmer's The Lovers (1952)[8] Octavia Butler's Xenogenesis novels (from 1987)[9] and China Miéville's Perdido Street Station (2000).

[12] In expressing his ambivalence with regard to science fiction, insectoids were on his mind when Carl Sagan complained of the type of story which "simply ignores what we know of molecular biology and Darwinian evolution....

I have...problems with films in which spiders 30 feet tall are menacing the cities of earth: Since insects and arachnids breathe by diffusion, such marauders would asphyxiate before they could savage their first metropolis".
