Urban Stingby

Urban Stingbies are -like creatures found in the Metro Kingdom of Super Mario Odyssey. Urban Stingbies bear little resemblance to their namesake bee-like counterparts outside of basic shape. Upon getting close to their larvae, they will transform into an Urban Stingby. When they spot Mario, they charge him in a straight line, exploding when they hit Mario or an obstacle. Urban Stingbies are normally found in alleyways in New Donk City in their larval form, and also appear in the Darker Side where they are always found in their adult form. Urban Stingbies cannot be captured, but can be defeated by throwing Cappy at them or attacking them with a jump, yielding a single coin. While in their larva form, they can additionally be defeated by simply kicking them away before they transform, making them completely inoffensive in this state.

Trivia

 * While the larval form is based on typical fly larvae (or "maggots"), mosquito larvae are actually not "maggots," but an aquatic tadpole-like creature.
