Reason: Extra Bees expands upon the bee breeding of Forestry by adding 107 new bee species to forestry. These bees cover a large spectrum of different effects and products, giving you the ability to produce everything from dyes to rare metal dusts purely from bees. It also adds the Apiarist Database, a tool to keep track of discovered species, mutations and traits. There are also new alveary components which help improve and streamline bee production.
