Cicada molting

This cicada came out its skin on this ash tree on the Purdue campus yesterday. This first picture was at about 3:14 pm, Aug. 25, 2009.

The big tree is a green ash tree (Fraxinus pennsylvanica) and is mentioned on the Purdue Tree Tour on the Green Trail:

In addition to providing a habitat for the cicadas, this ash tree also is home to a Laetiporus sulphureus fungus. This fungus will eventually rot the tree, but in the meantime the yellow chicken-of-the-woods fruiting body pops out of a damaged spot on the trunk now and then. It's not there now though. You can see the spot on the side of the tree facing State St. a couple feet above the ground.

About 3:38 pm, Aug. 25, 2009. The cicada has moved a few feet away from its old skin.
