Butterflies are just for pollination?There was an old tutorial on the forums here that's obviously buried pretty far in by this point... But the gist was that you take your forestry trees you want to breed together and put them in an enclosed space, butterflies will spawn from their leaf blocks and start pollinating the trees for you.
Speaking of tree breeding, I've never really messed with it before. Are there any pretty woods in Forestry? Right now I am using Sakura and Eucalyptus, which is fine, I like the colour scheme... but other woods would be nice
