## Grass/Bug damage taken

| Damage | Attacking types |
| --- | --- |
| 4× | [Fire](https://pokee.si/types/fire), [Flying](https://pokee.si/types/flying) |
| 2× | [Ice](https://pokee.si/types/ice), [Poison](https://pokee.si/types/poison), [Bug](https://pokee.si/types/bug), [Rock](https://pokee.si/types/rock) |

## Best types to use against Grass/Bug

To beat a Grass/Bug Pokémon, use Fire and Flying moves: they deal 4× damage. Ice, Poison, Bug and Rock moves also hit for 2×. Do not waste turns on Grass (¼×), Ground (¼×), Water (½×), Electric (½×) and Fighting (½×).

Grass/Bug and Bug/Grass are the same typing: in battle the order of a Pokémon's two types makes no difference, so a Bug/Grass search lands on this page too.

Going the other way, Grass and Bug moves between them hit Water, Grass, Ground, Psychic, Rock and Dark super effectively, but Fire, Poison, Flying and Steel take reduced or no damage from both.

6 Pokémon have the Grass/Bug typing, first appearing in Generation 1 and spanning 3 generations to Generation 5.

The highest base stat total is Leavanny with 500; the average across the group is 384.
