You are in for a TREAT!
******************
ROTFL. My dogs love to catch and eat them. Me...I can do without them.
A friend of mine from Toronto came to visit in August about 20 years ago and one managed to get back to Canada with her. She said it didn’t last long but while it did it reminded her of TN.
ANY AND ALL decorative trees in your yard should be netted before the onslaught.
Also, do what you can to protect woody landscape bushes and any flowering plants with branches.
In your area, the gorgeous redbud, dogwood and foxglove will suffer the brunt of their “attack”.
Many will die.
They lay their eggs under the bark, which they slice into with their ovipositor.
For humans, they are a nuisance and for insect-phobes, they are a nightmare.
They will fill the air around you like dragonflies in the swamp...only worse.
At the height of the hatch, they fly everywhere in short bursts and will land on anything at the end of their flight, often humans.
They are fun and I plan on going back to Chicago this summer to enjoy a day among them again.
