"It's Tough to be a Bug" is currently closed for refurbishment and it appears that the downtime of the queue is being used to also work on the Tree of Life.
A high reach crane is in position working on the upper areas of the structure. It isn't clear if this is work related to the structure itself, or installing upgrades for future nighttime shows at the park.
The area around the Tree of Life has been covered in safety netting since a part of a branch fell into the queue area in April 2012.
