Lepidopterist's Backpack

The Lepidopterist's Backpack is a portable storage utility added by Forestry. They can hold all varieties of Butterfly.

Usage
The Forestry backpacks have four modes. These modes can be toggled by crouching/sneaking and right clicking with the backpack in hand. The four modes are Normal Mode, Locked Mode, Receiving Mode, and Resupply Mode.


 * Normal Mode will automatically input picked up items as long as they are accepted in the backpack, and there is space for them. Crouch/sneak+Right clicking a chest with this mode enabled will dump all the backpacks contents into the chest.
 * Locked Mode will not pick up items. Chest interaction is the same as in Normal Mode.
 * Receiving Mode will act the same as in Normal Mode, except that chest interaction will put allowed items into the backpack, rather than out.
 * Resupply Mode is the same as Normal Mode in both item pickup and in chest interaction. Though, it will keep corresponding items in your inventory stocked to a full stack as long as possible.
