Novi residents expecting to hear the droning of millions of cicadas in the coming days may be disappointed (or delighted) to hear nothing out of the ordinary at all.
“Brood X,” the population of periodical cicadas which emerge from the ground just once every 17 years, has already begun to surface in multiple states across the country for the first time since 2004. Periodical cicadas spend years - either 13 or 17 years depending on the brood - feeding on roots underground in their larval state. Once mature, the adult cicadas emerge in massive numbers to sing loudly and reproduce for 1-2 weeks before they die.
Cicadas do not pose any threat to humans or animals because they’re not toxic and they don’t bite, but they can be destructive to plants. Females lay eggs inside young woody stems, like those on a tree or shrub, which can lead to the death of that branch. The loss of a few small branches poses little stress to a mature tree, but a young sapling may be badly damaged by female cicadas.
However, Brood X’s range extends only to select portions of Michigan and they’re not expected anywhere in Oakland County. Those interested in witnessing the natural spectacle can look to Washtenaw County as the nearest site where Brood X cicadas are expected to emerge. Annual cicadas, which emerge annually (as their name implies) and in much smaller numbers, will still surface in Novi as they do every year.
