Brood X cicadas are beginning to emerge.
DNR says this fascinating phenomenon is normal.
And even though cicadas look gruesome, will be loud and plentiful, and can damage some young trees, they are essentially harmless to humans and animals.
Currently, there are 12 different broods of 17-year periodical cicadas consisting of three different species.
Each brood is designated by a Roman numeral.
This is the year of Brood X. Brood X covers 15 states.
Indiana is also home to two annual cicada species that emerge May through August and peak in July.
Brood X nymphs will emerge when the soil temperatures about 8 inches underground reach 65 degrees.
A warm rain will often proceed large-scale emergence.
