The Brood XIX (and Brood IV stragglers) are all but gone, but annual species of cicadas are emerging around the United States right now. The various annual species of cicadas differ from periodical cicadas in many ways. Annual cicadas emerge in limited numbers every year, they are not organized into broods, they tend to be timid and camouflaged to match their environment, and while their life cycles are longer than a year, they are not as long as 13 or 17 years.
The most common annual cicada east of the Rockies is probably the various species of the Tibicen genus. There are also cicadas belonging to the Diceroprocta, Neocicada, and Okanagana genera out and about now.
Use the Insect Singers website to help match the species to their song.
Here’s one in my back yard in Oklahoma. It was fun to watch him emerge, wish I had caught it just a bit earlier in the process, but still pretty happy with the pics.
