They’re just starting. The hatching depends on ground temperature. Last time I remember shady areas in my neighborhood took a few extra days. It was deafening by Memorial Day 2007. We couldn’t prevent our lab puppy from eating them. We had to take him outside but as soon as his nose went down to the grass, it was full of cicadas. He kept getting sick!I have not heard or seen any yet this year
Next year will be the big brood everyone talks about. The periodical cicadas we have emerging now are a year too early. There are also the annual ones that come in late summer but they’re a different species. Those have a 2-5 yr cycle but some show up every year.
