Centiwings are long black arthropods with segmented bodies and protective, bright green shells. They have many legs which have a dark green coloration on their ends. Centiwings have two sets of antennae on each end of the body and have shiny, translucent red wings.
Centiwings are initially afraid of creatures until they have been in their presence for too long. Due to their flight, they are able to outpace most creatures once they become aggressive. Like other Centipedes, Centiwings are not stunned by Rubbish unless injured; however, they always drop held creatures when hit. Centiwings are also stunned for twice as long as other Centipedes. Despite being unable to hear, Centiwings still drop creatures and flee when a Cherrybomb is thrown. Centiwings can be killed with 3-4 Spears, though less are needed to make one flee. When severely injured, Centiwings begin to spasm and attempt to return to their dens. Like other Centipedes, Spore Puffs can be used to effectively dispatch them; this is especially effective with Centiwings, as their flying patterns commonly curl them up, allowing the Spore Puff's cloud to engulf more of the creature. Combined with the common spinning behavior of all centipedes that are stunned with a Cherrybomb, the player can make a relatively simple escape through throwing both items at a Centiwing in timed succession, or sneaking up and ending a possible confrontation before it ever begins.
Centiwings are almost always moving, making sneaking past one very difficult. Their flight combined with their ability to quickly crawl through tunnels and along poles makes them capable of covering entire rooms in a short amount of time, leaving little room to go unnoticed. However, Centiwings cannot see very far, and are incapable of hearing. Crouching and crawling reduces their vision further. Moving swiftly can help to avoid detection, as well as seeking cover beneath level geometry or within tunnels.
Centiwings spawn exclusively in Sky Islands for most Slugcats, meaning they are avoidable by skipping it entirely. However, when passing through the region, they are a common threat. A player can take advantage of the short window that Centiwings fear them to pass through rooms without any danger. Centiwings are normally found flying through the upper areas of a room. Taking a lower path through the room, when possible, can help to avoid them.
Centiwings grab on to creatures by their heads. If they manage to latch on with both ends of their bodies, they deliver a shock. Rather than deal a set amount of damage, Centiwing shocks either kill or stun the creature depending on its mass in relation to the Centiwing. If it weighs less than the Centiwing, it dies. When injured and attempting to retreat inside of a den, Centiwings can latch on to creatures and pull them inside of the den, killing them like Pole Plants and Monster Kelp.
Centiwings have a unique timer for determining aggression. Upon seeing a creature, they start a countdown in which they consider the creature a threat for 7.5 seconds. They become progressively less afraid as the timer ticks down, and once it reaches 0, they grow progressively more aggressive towards the creature. Once they consider a creature prey, they begin pursuing it in an attempt to kill it. Every creature has its own individual timer once noticed. These timers can run simultaneously, and do not interrupt each other. This timer can be paused by stunning the Centiwing with Spears or Rubbish, but resumes shortly after.

Unlike other Centipedes, Centiwings do not have fully movement-based vision. While their vision does improve when something nearby moves, they are able to see to an extent constantly. Centiwings can detect Slugcat even when they are crouching and idle. However, crouching still reduces a Centiwing's vision. Centiwings have a small vision cone in comparison to other Centipedes, meaning they are much less likely to notice Slugcat, or other creatures, altogether.

Centiwings do not have a large variety in appearance. Centiwings can be 12 or 13 segments long, and their shell colors have a slight range from a warm to cool green. Their shell colors can be affected by a room's darkness.
