Lost Wings

Two pairs of insect wings stuck to the side of a car window with no trace of the bug they used to belong to. The wings a framed by a blurred tree that acts as a background to make their translucent shape clearly visibly. Farther to the back is an office building that's also out of focus due to the narrow depth of field.

I'm not sure what bug left these stuck to my car window, but it must like walking.
