If you have a butterfly you do not use as often or want to make more room for new species from events or core sets, you can place these butterflies into storage.
Butterflies can be placed in storage by tapping the “Store” action icon at the bottom of the screen when tapping on the selected butterfly. You can go back to them at any time by going to Menu > Inventory and then selecting the Storage tab. You can store butterflies, caterpillars and bees. But not eggs, pupa, the beefly or Doug.
Please note: Storing a butterfly will reset the ability - when you take it out of your inventory you will have to wait for it to be ready again, so choose which species you store wisely!
Return them to the forest by tapping Menu > Inventory > Storage. This is where your stored butterflies live. Tap on the species, then tap “Return”. You’ll need to have enough space in your forest.
Sometimes if there is no room in your forest an egg or Doug can go to your storage automatically.
