Grass-types are very strong against Water (as per the Starter triad), and can also pose trouble for Rock and Ground types. However, they are likewise very weak against Fire, and take heavy damage from Flying and Ice types. Bug and Poison also are super-effective against Grass. Grass types often have high speed and/or evasion, which can sometimes circumvent elemental weaknesses.

Even their resistances to Ground and Fighting, the two types with the most offensive coverage, are of little use since many Pokémon of both types can learn Rock moves. However, dual-type Bug/Flying and Bug/Poison Pokémon have an outstanding double resistance to Fighting, which can make up for their low Defense.

Furthermore, many fully-evolved Bug-type Pokémon have a base stat total below 400. Although they are super effective against Psychic, Dark, and Grass types, Bug types are unable to deal a lot of damage to many other types, as seven types (Fire, Flying, Fighting, Poison, Ghost, Steel, and Fairy) resist Bug-type moves.

Until Pokémon Platinum, several Bug-type Pokémon (Shuckle, Kricketot, Burmy, Wormadam, and Combee) were unable to learn any Bug-type moves naturally. Each of them is now able to learn Bug Bite by level up. In Generation I, the Bug type is super effective against Poison-type Pokémon, while the Poison type is super effective against Bug-type Pokémon. As such, this was the only case when two different types were super-effective against each other. The Bug type was the most common 4× weakness in Generation I, with 11 Pokémon doubly weak to it, mainly due to Poison type having a weakness to it at the time. No Pokémon gains the Bug type upon evolving that did not already have it.
