Cicada's? They go bye byes about 2200 or when it get fully dark out here. Can you tell the difference between them and black crickets which sing away during the hours of darkness?

Definitely cicadas. I've had a brief poke around on the 'net to find out why they are making noise at night, apparently can happen near artificial light sources or if they're overcrowded or if the weather's hot.

The NZ ones have a 3-5 yr cycle , the longest are some in the US , at 13 & 17yrs , but a lot at less yrs than that

And of that 3-4 yr cycle only 3-4 weeks are spent above ground .Makes interesting reading
