His sister noticed it had blue eyes. The family took pictures of the cicada and then released it back into the yard.

Later, they discovered how rare blue-eyed cicadas are, so they found it again.

It is now the first blue-eyed cicada in the Field Museum's collection, which is over a century old.

The insect has rare mutation that is "one in a million," experts say. The mutation causes cicadas red eyes to be gray-ish blue instead.

The cicada is on display at the museum. More information about how to see it can be found on their website's event page.
