Extra Bees is a Minecraft mod by Binnie, which extends the bee breeding system of Forestry.
It adds 111 new bee species, along with many new products and effects.
It adds the Indexer, a machine to store your bees and easily find them again.
There is also an apiarist database to keep track of discovered species and mutations.
Using genetic machines, you can convert bees into Liquid DNA and extract their genes.
You can then insert these genes into any other bee, easily transfering genetic material.
