Trite

The Trite is an enemy found in Doom 3. Trites resemble spiders, have an upside-down human-like head, and possess many eyes. They usually attack in swarms, and are rarely seen alone.

Trites attack by lunging towards the player, or by biting at close range. In groups, Trites can be deadly and can be considered a major threat, especially when many attack the player at once. Fortunately, Trites do not appear in huge groups often, and they have a low amount of HP, so only a couple of pistol shots are needed to kill one. Another good weapon to use against Trites (especially when you are greatly outnumbered by them) is the Machine gun. Trites die differently from other enemies; they curl up into a ball and explode in a splash of green blood.

They tend to surprise the player by crawling out of narrow spaces where the player cannot fit, or by dropping from ceilings with the aid of spider thread.

The concept for the trite was likely based around one of the creatures from the movie, The Thing, in which a creature's (imitating a human) head falls off on the ground, lands upside-down, and grows spider legs and crawls away, with the head staying upside-down.

Trivia:
The name "Trite" means two things:

1. A type of jumping spider.

2. A synonym for the term "overused".

Trites appearance is similar to that of Ticks. This could suggest that that they are either related as different species are the same species but of different ages (Trites could simply be older ticks,) or they are actually different sexes of the same species.

Owing to their spider appearance and tendency to appear around Vagaries, it is conceivable to think that perhaps Vagaries are Adult or "Queen" Trites.
