Though they aren't aquatic, cicadas can end up on the surface of trout streams in great numbers in the rare years when they swarm our forests by the tens of millions. It stands to reason that trout would gorge themselves on cicadas at such times, and I have heard reports of it but never been lucky enough to witness the "cicada hatch" myself.
My brother and I have a disagreement about bugs from our childhood.
I remember a swarm of cicadas (17-year locusts), and I'm trying to place the year. It would be 1954 to 1959, I believe. I remember the cicadas' distinctive call ringing through the summer (spring?) night. They covered anything that shed light—lampposts, storefront windows, porch lights. They were about in huge numbers. When you walked down the street, you couldn't avoid stepping on them, and they crunched. (Big bugs.)
My brother says he only recalls a mayfly swarm—post 1959—that was so bad it caused auto accidents on the freeway because cars ran over the mayfly bodies and collectively they were greasy and caused cars to skid.
So does anyone out there remember either of these events. I think both probably occurred. We'd like to pin down the years.
