This video from the California Academy of Sciences in the USA says about itself:
Academy biologist Sarab provides a behind the scenes look into the leafcutter ant (Atta cephalotes) exhibit in the Rainforests of the World exhibit. Leafcutter ants carry leaves under ground to use as a base for farming fungus, their only food. Sarab also demonstrates how butterflies are released into the rainforest exhibit on a daily basis. (To see what happens with the butterfly pupa in the Insect Holding Room before they emerge and are released into the exhibit, watch a behind the scenes video here: http://bit.ly/c2Vy2h )
