Are you in Northern California? The late 70's drought seemed to render them extinct - along with a while lot of other species like Jerusalem crickets that I used to see all the time when I was growing up in Marin County.
I'm sure the Midwest still has trillions of them, though. :)
Nope, western MD and we sure have not had any droughts.
In fact, it’s “monsoon season” from February to late May.
Maybe too much rain?
I sure miss them, though.
