Bees. Flowers. They go hand in hand. :) (yeah, might like to create a private modpack with Forestry, Binnie Bees, Magic Bees, and Botania)

I'm not sure what the bee tech tree would look like, but I think thinking something like -

The initial bee might be a steadfast bee (that bee needs a use now that marble bees are long gone) tossed into a manapool. Could be an alternate way to generate botania flowers (like forestry bees do for normal flowers). Maybe they can produce quicker Royal Jelly? (I'm on a 1.4.7 FTB nostalgic kick right now)
Mana Bee (?) - "Flower" is a mana pool
Elfen Bee - "Flower" is one of the pylons. (mutated from Mana Bee and maybe the steadfast bee, or some descendant of that bee - is the Heroic Bee still in Binnie Bees?)
