I'm pretty sure you encounter in in science fiction as well, where some bug like alien has a carapace or a soldier has some armored exo-skeleton described by the word. Though I cannot think of any specific examples.

Quite common in videogames, too.

A specific example would be the Carapace (armor) upgrades in Starcraft 2 (one faction, the Zerg, are basically insects).

Also sometimes used for (humanoid) armor crafted from shells (fantasy settings).

I think this is MUCH more prevalent in scifi/fantasy targeted at male audiences, and the data confirms it [1]

The Dota 2 hero Nyx Assassin (beetle-like creature) has a skill called Spiked Carapace.
