Color-bugs
The Color-bugs are among the most disturbing phenomena Ralph Roberts and Lois Chasse encounter after their perception ascends to the hyper-real level. These creatures, which resemble prehistoric trilobites, are visible only to those who have stepped beyond ordinary reality, and they swarm in grotesque profusion around the Derry Civic Center on the day of Susan Day's scheduled speech, serving as a nauseating harbinger of the deathbag that hangs over the building.
Appearance and Behavior
The Color-bugs are described as giant bugs that look like prehistoric trilobites, squirming in and out of the evergreen bushes lining the Civic Center's walls in droves, crawling over each other, bumping heads, and sometimes rearing up and pawing each other with their front legs like stags locking horns during mating season. They are not entirely transparent but have a ghostly, unreal quality, their auras flickering feverishly and brainlessly through a whole spectrum of colors, so bright and yet so ephemeral that they can almost be mistaken for weird lightning-bugs. They move with a dazed sluggishness, like flies buzzing against a windowpane in November, and leave slimy trails of color behind them that quickly dim and fade. Some emerge from the tops of the bushes and ooze aimlessly up the wall, while others crawl out from beneath the bushes onto the small strip of lawn.
Interaction with the Unaware
The Color-bugs exist on a plane of reality invisible to ordinary people, yet they interact with them in unsettling ways. When John Kirkland, a local news commentator, and his producer walk onto the lawn, they pass directly into a knot of the twitching, crawling trilobites. One bug climbs onto Kirkland's polished loafer and then onto his pantsleg, apparently bound for his crotch, while another finds its way onto the producer's shoe and works its way up her leg, disappearing beneath the hem of her skirt. The producer feels something, absently scratching at the lump as it climbs, and when the fragile, flabby thing bursts, its innards drip down her nyloned leg like pus, remaining there unseen and unsuspected until her evening shower. Another bug crawls onto Kirkland's red tie, apparently bound for his face, and one even squirms slowly into his mouth. The two continue their conversation, exchanging quips and ideas about covering the rally, totally unaware of the creatures crawling over them.
Connection to the Deathbag
The Color-bugs are intimately connected to the vast, oppressive deathbag that surrounds the Civic Center. Ralph and Lois feel the deathbag pressing in on them, trying to overwhelm them with feelings of loss and despair, and it is within this gloomy, suffocating presence that the bugs thrive. The bugs seem to be drawn to the deathbag, feeding on the negative energy it generates, and their presence is a visible sign of the impending catastrophe. The deathbag itself is described as having a sluggish, half-sentient life, and the bugs appear to be a part of that life, a manifestation of the decay and death that is about to occur.
Significance
The Color-bugs serve as a powerful symbol of the unseen forces at work in Derry, and of the way that ordinary people are oblivious to the supernatural dangers that surround them. They are a grotesque reminder of the fragility of life and the thinness of the veil between the ordinary world and the world of auras and deathbags. Their presence at the Civic Center underscores the scale of the impending tragedy and the helplessness of the people who are about to become its victims. They are also a testament to the heightened perception that Ralph and Lois have achieved, allowing them to see the true horror that lurks just beneath the surface of everyday reality.
