The Bug Egg Group (Japanese: 虫グループBug Group) is one of the fifteen Egg Groups. As of Generation VII, 79 Pokémon belong to this group.
Most Bug-type Pokémon fall into this Egg Group, making its characteristics similar to that of the Bug-type itself. Other arthropod Pokémon such as Drapion, Gliscor and Flygon are also included in this group, despite not actually being Bug types.
In this Egg Group, moves are not passed down as easily, as most base-level Bug Pokémon cannot learn any moves by breeding. Also there is a notably small amount of Pokémon that are in this group and another, making chain breeding difficult as well. The Pokémon of this Egg Group have a number of unique ways of evolving.
