If your a native of Butcherblock by the time you find them they will con green to you. They rarely group, they usualy drop 1 silk or more and spider legs. They are most common around the two shops along the road to the zone line into Greater Faydrak. They may spawn in other places in butcherblock, buth this is where i can consistantly find them. They are good for young tailors to kill, since they are the lowest level spider you can kill and still get spider silk. Hope this helps.
