In Generation I only, Bug-type moves were super effective against Poison-type Pokémon and Poison-type moves were super effective against Bug-type Pokémon.
As of Generation IX, there are 94 Bug-type Pokémon or 9.14% of all Pokémon, making it the 6th most common type after Psychic and before Fire and Poison.
As of Generation IX, there are 34 Bug-type moves, which makes up 3.64% of all moves (excluding those that are Bug-type only under certain circumstances), causing it to tie with Ghost and Fairy as the 4th rarest type among moves, after Ice and before Poison.

Abilities
Interacting with the Bug type
A Pokémon with Protean or Libero will become a Bug-type Pokémon if it uses a Bug-type move. A Pokémon with Color Change, Imposter, RKS System, or Multitype will become a Bug-type Pokémon if (respectively) it is hit with a Bug-type move, is sent out against a Bug-type opponent, is holding a Bug Memory, or is holding an Insect Plate or Buginium Z.
Unlike in the core series games, in Pokémon Sleep, each Pokémon can only have one type, which determines the kind of Berry that the Pokémon will gather for Snorlax to feed on. Bug-type Pokémon will gather Lum Berries, and typically have the Dozing sleep type.
The following is a list of Bug-type Pokémon in Pokémon Sleep.
Due to the decreased amount of types in the TCG, Bug-type Pokémon are generally listed as Grass-type Pokémon.
Grass-type Pokémon in the TCG are generally weak to Fire-type Pokémon and have no resistance. They are strong against some Fighting and Darkness Pokémon, and until Sword & Shield were strong against some Water types as well, whilst Metal Pokémon resisted it until the EX Power Keepers expansion set before this resistance was brought back in Sword & Shield.
The Bug type has been paired with every other type except for Dragon and Normal.
This makes the Bug type the only type to not have been paired up with Dragon.
Generation V introduced the most Bug-type Pokémon of any Generation, with 18, and Generation VI introduced the fewest Bug-type Pokémon, with three.
Generation IV introduced the most Bug-type moves of any Generation, with seven, and Generation IX introduced the fewest Bug-type moves, with two.
The Flying type is one of the two types most commonly paired with the Bug type, with the other type being Poison. However, there are a number of Bug types that are not Flying-types nor have the Ability Levitate despite being able to fly, such as Beedrill and Venomoth.
Despite this, the only Bug-type Pokémon that can learn the move Fly, Volcarona, Genesect, and Vikavolt, are not Flying-type Pokémon.
Out of these three Pokémon, Vikavolt is the only one that could not learn Fly in its introductory generation; Vikavolt was made able to learn Fly at level 50 and from TM06 in Pokémon Sword and Shield.
Pinsir and the Ledyba evolutionary line were also unable to learn any Bug-type moves naturally until Generation IV, in which the former gained access to X-Scissor and the latter to Silver Wind and Bug Buzz via 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 ever super effective against each other.
Additionally, since Generation I, the Bug and Fighting types are the only two separate types that resist 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.
Each of the three first partner Pokémon types have a different effectiveness when attacking a pure Bug-type Pokémon (Grass does ½× damage, Water does 1× damage, and Fire does 2× damage).
This trait is also shared with pure Steel-type Pokémon.
No Pokémon gains the Bug type upon Evolution that did not already have it. It shares this distinction with the Normal type.
Additionally, no Pokémon gains the Bug type upon changing forms with the exceptions of Arceus and Silvally, which can change into any type.
