Brood X cicadas will soon swarm the East Coast, but South Dakotans need not worry
As temperatures warm, South Dakotans will box up their sweaters in favor of T-shirts, prop open their windows and emerge from a long, wintery hibernation.
And cicadas — those bugs that give a perpetual radio static to hot summer days — will also make an appearance after spending a considerable amount of time lying dormant underground.
Brood X, a large population of cicadas that emerges just once every 17 years, will be joining the annual batch of buzzing insects in 2021, particularly on the East Coast and in the Midwest. Entomologists at Virginia Tech estimate there can be as many as 1.5 million of these cicadas per acre, meaning that trillions will soon awaken from their slumbers.
But, South Dakotans need not worry, because no Brood X cicadas call the state home.
That’s according to Amanda Bachmann, an urban entomology field specialist with South Dakota State University Extension. In fact, South Dakota residents should only expect one species — known as the dog-day cicadas — which won’t appear until late July or early August.
“Our cicadas do not show up that early,” Bachmann said. “The large insect that shows up in May and June that tends to get a lot of attention is the June beetle, or June bug.”
Similar to cicadas, June bugs overwinter in the soil and emerge as the ground warms. They also make a slight buzzing noise, but could just as likely to startle you by banging against a window screen.
The beetles are typically about one-half to an inch long and range in color from a light red to a dark brown-red, according to the SDSU Extension office. While nocturnal, the oval-shaped bugs are attracted to light and are often found underneath garage and street lights.
