From Bulbapedia, the community-driven Pokémon encyclopedia.
The Bug Egg Group (Japanese: 虫グループ Bug Group) is one of the fifteen Egg Groups. As of Generation IX, 92 Pokémon belong to this group.
Characteristics
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.
Prior to Generation VIII, the Trapinch family were exclusive to the Bug egg group.
