Mellifers (ME-li-fuhr) are bee-like creatures that live and operate as part of a swarm with a hive mentality. The leader of a Mellifer hive is referred to as a Mellischwuler. Their hives are large and are where they harvest their own venom to use as a weapon. They have a connection with regular bees and often use them to provide cover for their movements. Mellifers' only natural enemies are Hexenbiests. Mellifers are the only Wesen seen thus far who are openly friendly towards the Grimms.
