A new, larger type of cicada is emerging – and they have big black eyes and “like to scream”


Billions of Brood X cicadas emerged temporarily this summer after being underground for 17 years. They had only been there a few weeks – but now a new, bigger type of cicada has arrived to take their place.

Officials from Maryland’s Catoctin Mountain Park, a unit of the National Park Service, said the bugs are called dog cicadas because they come out “during hot dog days of summer.” The insect has bright green transparent wings and large eyes, and it takes two to three years for this particular type of cicada to develop and emerge from the basement. But unlike brood X, the population makes its appearance every year.

“They are much bigger and have black eyes,” Catoctin Mountain Park wrote in a Facebook post. “Like all cicadas, they are harmless and like to scream.”

Do you think the cicadas are gone? Think again ! Now that periodic cicadas have completed their lifecycle, it’s time to …

Canine cicadas also have a predator looking for them, the cicada killer wasp. According to the Ohio State University, the wasp does not feed on periodic cicadas, such as Brood X, and can soon be seen searching the woods for its “exclusive prey.” These wasps are one of the largest found in Ohio, measuring up to 1 5/8 inches in length. Although they are large and appear worrisome, researchers at Ohio University say they are not dangerous and rarely sting.

This species of cicada appears in various states. Twitter users posted that they had seen them in New Hampshire, Maryland and Ohio, and the United States Fish and Wildlife Service says they can be found from Dakotas and Oklahoma to Maine and South Carolina.

The University of Arkansas Arthropod Museum says they usually emerge in July. Adults can grow to over an inch long and half an inch wide, according to Texas A&M University. Summer is when they very audibly begin their mating process. According to the university, male cicadas will rest on tree trunks and branches and “sing” to attract the attention of female cicadas.
