Dusk is the time of day between sunset and night. Many species of Megatibicen & Neotibicen (formerly Tibicen) sing at this time. I’m not sure why they sing at this time — perhaps it helps them avoid audio competition with other singing insects, or perhaps it helps them avoid predators by calling at this specific time of the day.
If you find yourself outdoors in the eastern half of the U.S. after sunset and hear a cicada call, it is likely one of the following Megatibicen or Neotibicen species:

Have them in central FL now and they don’t quite match any of these sounds. These sounds like high-pitched chirps in almost a sleigh-bell rhythm.
I found one in my yard in Northern Colorado in 2018 got pics to prove it, isn’t that odd to find one in Colorado?
Maybe — depends on the species. cicadamania@gmail.com
Will the cicadas still emerge even when it’s a cooler than normal evening? Like the 60s?
Hi Cameron,
I wouldn’t bother looking unless it was in the 70s, and if you want the best chance, and night in the 80s.
Since we’re headed for a relatively cold August, try for nights in the 70s, not 80s like I said.
Hey Dan, I’m planning a day one day next week to travel to south Jersey around the pine barrens to search for Neotibicen Auletes nymphs. Where do you think would be the best place down there to look?
I’ve heard them as far north as Rumson all the way south to Cape May. That said, I’ve only went looking for them and found them in Manchester.
I live in Arizona and the annual cicadas “sing” all day during Monsoon season (June 15-September 30). They seem to get louder the more humid it gets. Is that odd?
I was born and raised in Southern California and never once heard or saw a cicada.
Arizona has a lot of cicadas, in particular: Cacama, Diceroprocta, Hadoa, and Okanagana are common. Here is a list: https://www.cicadamania.com/genera/usa.php?qs=AZ&category=A&q=#speciesresults
Megatibicen (formerly Tibicen) cultriformis is also active in the later summer, and tends to sing from tall trees along rivers.
