I have a lot of Redbuds and they have been damaged by the annual infestation but not killed. I hope they feast on English Ivy. That stuff is a plague.
Back in the early ‘70s, Hillsboro High School in Nashville did not have air conditioning and it was difficult to hear the teacher over the sound of the cicadas. We called them locusts which is incorrect but traditional like calling bison “buffalos”.
They really like those big suburban yards and like fireflies seem thicker in the suburbs than in the country.
They can fly but not well so when mowing the grass, they often errantly fly and smack into the yard boy (me). Fortunately, they don’t all take wing at once in swarms.
