When the irises begin to bloom, expect up to 1.5 million cicadas per acre to begin boiling out of the ground. This spring Indiana will see the emergence of the 17-year cicadas (Brood X). Once every 17 years they emerge en masse, climb up trees, sing (though it sounds more like screaming), mate, and lay their eggs on the tips of tree branches. Help us learn:

Where are they?

When the irises begin to bloom, expect up to 1.5 million cicadas per acre to begin boiling out of the ground. This spring Indiana will see the emergence of the 17-year cicadas (Brood X). Once every 17 years they emerge en masse, climb up trees, sing (though it sounds more like screaming), mate, and lay their eggs on the tips of tree branches. Help us learn:
-
Where are they?
The distribution of 17-year cicadas has changed a lot in the last 200 years! We aim to learn where these insects can still be found in Indiana.
-
When do they emerge?
Cicadas will emerge at different times throughout the state. We’d like to learn how the timing of 17-year cicada emergence is impacted by surrounding land use.
