Vespiquen, the Pokémon you might be referring to, can typically be found in areas with a lot of flowers, like forests or gardens. In the Pokémon games, it often appears in regions where Honey can be used, such as in the Sinnoh and Unova regions. Additionally, it can evolve from Combee, which you can catch in similar environments. Always check specific game guides for the exact locations in your version.
