When a character is poor, there's no better way for him to say "I have no money" (due to Perpetual Poverty or a Broke Episode) than to have moths emerge from his wallet when he opens it. It's also the perfect way to show that a character with tons of money at his disposal is a complete skinflint. Alternately, the character can make a great show of pulling the pockets of his pants inside out (an act that might also be accompanied by the appearance of moths). Double points if the character does both.
For the most part, this is an Animation Trope, possibly because actors don't much like fragile flying insects in their pockets, though it isn't often used anymore even in cartoons. Little to no relation with Macabre Moth Motif and Moth Menace. Contrast Bat Scare, in which the startling appearance of flying creatures indicates a location is unexplored or abandoned. Compare Bankruptcy Barrel.
- Pokémon: Happens to Team Rocket regularly.
- Justified in the anime adaptation of JoJo's Bizarre Adventure: Vento Aureo. After Giorno returns a purse stolen by a pickpocket, its owner opens it and a pair of moths fly out.

Moth: Oh, thank you madam! If it weren't for you, I feared I would never again see the light of the sun.
