A blue-eyed cicada was found by Carole Will McDonald, of Niles, in early June. She said she found the critter near her home near the area of Milwaukee Avenue and Oakton Street.

One of the blue-eyed creatures found in the Chicago suburbs was donated by a family to the Field Museum , the museum announced in a press release Wednesday.

A 4-year-old boy in Wheaton, Illinois, found a blue-eyed cicada in his yard, according to Smithsonian magazine. The family ultimately donated the insect to the Field Museum in Chicago.
