Thanks for the insight, Matt! Yes, I do notice all the great pollinators we have around.
So I actually went down a rabbit hole looking into this, and it turns out what I was hearing are cicadas, specifically Cactus Dodgers.
“The cicada falls into one of two major groups, one called “dog day,” the other called “periodical.” The dog-day cicadas, which usually appear during the hottest days of summer, hence the name, include all of the several dozen species of the Southwest. They have a life cycle of two to five years. The better known include the Apache cicada, marked by a tan band around the back of its head, and the cactus dodger, noted for the male’s frenzied courtship behavior among the desert’s prickly pear and cholla cacti.” From Desert USA
Here’s what it looks and sounds like.
