yes , parasect, paris, wormadam,
If I understand your question correctly, Dark, Psychic, and Grass are weak against Bug.
no i think torterra or sceptile because they have great damage on the opponents Pokemon and they both have dual types sceptile can learn dragon type moves and fighting- blafreen Scyther Is "Bug" Type
fire, grass, fighting, poison, psychic and steel I'm pretty sure. if the Pokemon you are battling has another type other than bug (eg poison) than a Pokemon that is effective against both types would be helpful (grass for a bug/poison) i hope this helps.
It is a attack type from a Bug type
Torterra is a Grass and Ground type pokemon.
Of course, a Grass type Pokémon can defeat a Bug type Pokémon. But Grass type moves are "Not very effective" against Bug type Pokémon, meaning the power of the Grass type move is halved.
Leavanny is a Grass and Bug type pokemon.
Wormadam is a Bug and Grass type pokemon.
Swadloon is a Grass and Bug type pokemon.
Catterpie, Roselia, Scyther and many many more grass type Pokemon can learn bug type moves.
Parasect is the dual Bug/Grass-type Pokemon.
Paras is the dual Bug/Grass-type Pokemon.
No, it is a Grass/Bug type.
