Actually, Corellian Butterflies are quite a challenge if you're alone and around the same combat level. They have a long ranged attack and quickly help each other out if one is attacked. If you are below their combat level, hit the burst run and fast! If you're well above their level, then "Move along," nothing to worry about. Several variations of the Corellian Butterfly exist. Only Corellian Butterflies and Dalyrakes offer Corellian Insect Meat, which is required for Corellian Camo Kits, useful for crafters who have to brave the wild while checking on their harvesters.
