FTB Unleashed - Butterflys?

[LazerusKI]

I have read two different things about how to find them.
1) They spawn only near forestry trees
2) They spawn randomly

so...how to find them?

They spawn on forestry tree leaves. (I think they need light too)

Any forestry tree will work- so you can just analyse vanilla saplings (get several types and you'll see what they do)
​

You're best off doing this inside- otherwise they fly off.

Be warned, you'll need to right-click with a scoop to catch them, and they can be a pain to catch thanks to their weird hitbox (you have to right-click the top surface of the block they're sitting on, not on the butterfly itself.

Also, they're addictive. MASSIVELY addictive.
