Cicadas appearing in Iowa after 17 years

Posted: Updated:

Periodical cicadas are appearing in the Iowa woods after living underground for 17 years.

These red-eyed periodical cicadas are found in southeastern Iowa, Missouri and Illinois with other breeds coming out at different times in the U.S. The best place to find them is in native woodlands.

Periodical cicadas can't chew and will feed only on sap, posing little threat to plants. They will not bite or sting.

Adult male periodical cicadas will "sing" from late morning through early afternoon for five or six weeks after hatching. This singing can be incredibly loud due to the high cicada population during each cycle.

Iowans who see these cicadas are encouraged to report their sightings to the National Geographic Society Magicicada Mapping Project at www.magicicada.org to help researchers better understand these insects.

Fore more information on periodical cicadas, you can visit the Iowa State University Department of Entomology's website.
