(UNDATED) - Some northwestern Indiana residents may soon hear the mating call of an insect that appears only once every 17 years.
After spending the last 17 years underground feeding on tree roots, periodical cicadas will resurface later this month in Lake, Laporte, and Porter counties, filling the air with their loud love song.
Entomologists say it shouldn't be hard for bug lovers to view and hear the insects. Millions of them -- up to 1-point-5 million per acre -- will fill tree branches for about six weeks.
Adventurous eaters who are annoyed by the cicadas' shrill symphony have another option. Biologists say the bugs are edible, but should not be eaten by people who are allergic to shellfish.
