Annual Cicada

Cliff Sadof, Entomologist

Annual cicadas have been quite abundant this year. They cause no real injury. They emerge later in the year (late July - September) than periodic cicadas (May - June). People are just a bit concerned about the pupal skins on the trees. (Click on smaller images below to see larger images.)
