ARGH! I've been using the 'Charms Type Chart for all my strategy, and it turns out it's wrong! It says that Bug-type attacks are only normally effective against Psychic pkmn. After Plapti & Sem both said Bug attacks are Super Effective against Psychic pkmn, I checked in the Prima Guide for Diamond & Pearl, figured it was something new for 4th gen - then checked in the Prima Pokedex for the 3rd gen, and saw it's the bloody 'Charms chart that's wrong!!! ARGH!!!!!! Not Happy. Would like to eviscerate the miscreant responsible with a spork. I guess you can lock this topic when it's fixed, but please check the chart line by line so I don't have to do that myself.
