It’s been 17 years, and the cicadas are back! We have Brood XIII cicadas. Friday, only a couple. Saturday morning, we were looking for them at a forest preserve a few towns away, but not seeing much. Saturday afternoon, hundreds in our yard. Today, maybe thousands! I don’t think I’ll be walking on the grass for a while. The pale cicada has just emerged from the nymph exoskeleton, and will soon look like the other one. They are all over the grass, on daylily foliage, and on a burning bush. Mostly, they are covering the trunk of honey locust trees in my neighborhood. This neighborhood didn’t have many cicadas 17 years ago, though a park with large oak trees a few blocks away did.
