Sorry, I'm not sure what happened to the reply sent October 5th but in any event, that appears to be insect damage on your chokecherry most likely caused by a Japanese Beetle. Japanese Beetles feed on leaf tissue of many different species of plants but they leave the veins so their feeding causes a distinctive lacy pattern.
Japanese Beetles are gone at this point in the season having burrowed underground where they will spend the winter and the leaves will fall soon so there is nothing we recommend you do this year to manage them.
Here is a link to CSU Extension fact sheet with more information about Japanese Beetles:
