The Concept Bee addon adds two bee varieties to Minecraft Bedrock Edition. No, they are both peaceful creatures and will never attack first. They differ only in textures. The bees that Concept Bee adds will populate all the warm biomes in Minecraft Bedrock Edition.
The Concept Bee addon is great for making Minecraft BE better. You can find their nests in the MCBE on the trees. Not at all, of course. There is a craft in the recipe book on how to create a beehive in MCPE. A great way to get honey.
