Depiction in the seriesA parasprite infestation in Ponyville is the subject of the episode Swarm of the Century. Fluttershy encounters a single parasprite, who chirps at her and endears itself to her. When she tries to feed it, it eats an entire basket of apples in mere seconds. Fluttershy unwittingly brings it into town to show to her friends, who are all unfamiliar with the creature and become enamored with it, except Pinkie Pie who storms off in search of musical instruments. The ponies' adopted parasprites become huge swarms overnight; it is only then that the ponies discover that parasprites can quickly and asexually reproduce by coughing up another parasprite. The pests relentlessly devour crops and food, but are able to consume wood, fabric, and inorganic materials after Twilight Sparkle casts a spell to stop them from eating food. The ponies make several attempts to round up the parasprites, but the pests keep getting loose. Twilight runs to Zecora's hut and consults her, but Zecora offers no solution.
- "Tales of crops and harvests consumed. If these creatures are in Ponyville... you're doomed."
- — Zecora
During the first duel between Twilight and Trixie in Magic Duel, Twilight magically summons a single parasprite, which eats multiple pies and their tins then coughs up a second parasprite. Twilight quickly disposes of them both before they can cause trouble like before.
In Grannies Gone Wild, some parasprites appear on an arcade game console.

Parasprites in groups of seventeen are one of the four types of obstacles in Rainbow Dash's Rainboom Game. The in-game How to Play instructions show them in a group of three, and the Hubworld website's How to Play instructions refer to them as balloons.
Parasprites are the focus of the game Swarm of the Parasprites. Some of the parasprite varieties that appear in this game are exclusive to it.
A swarm of parasprites is shown in the Ruckus Reader interactive storybook Things That Go Bump in the Night. They appear in the imagination of Applejack, who refers to them as "mean bugs [who] want to eat our food".
In the mobile game, they appear as barriers, needing multiple of an Element of Harmony's shard (depending on color) to make them disappear. They usually appear in swarms of 5.

On the Brown Parasprite Enterplay collectible trading card, the quote says: "What is the airspeed velocity of an unladen parasprite?" This is a reference to Monty Python and the Holy Grail where parasprite is replaced with swallow.

PARASPRITES may seem sweet and innocent, but feeding these little insects may cause more trouble than they're worth. Their gluttonous appetites cause them to rapidly multiply, quickly turning them from pets to pests.
