From Bulbapedia, the community-driven Pokémon encyclopedia.
The Bug Egg group (Japanese: むし Bug) is one of the fifteen Egg groups.
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.
