ALL YOU SCIENTIST, ENTOMOLOGY, biology types out there, I need your input to solve a mystery. I suppose I could google the topic, but I’d rather read your theories or fact-based conclusions.
Last Sunday afternoon while walking on the grounds of Valley Grove Church, rural Nerstrand, I heard a buzzing. Like a zillion bees. At first I thought I was hearing things because, when I would stop, the droning also stopped.
I questioned whether I could be suffering from tinnitus, an occasional issue given my hearing loss. I’m nearly deaf in the my right ear which causes all sorts of problems in determining sound sources and in hearing in general.
But this buzzing seemed real. I risked asking my husband if he heard what I heard. He did. We paused on the dormant dried grass. No buzzing. Then we took a few steps and the irritating hum resumed. Then my observant husband, with the way better vision than me, saw the flies. Everywhere. Infinite numbers settled on the grass as if sunning themselves. I strained to see the camouflaged flies and then photograph them. I managed one image of a single fly. Whenever either of us moved, they, too, moved. It was the craziest thing.
I’m a woman who has a history with flies. They were part of my growing up environment on a southwestern Minnesota dairy farm. A fly swatter was always at the ready. Sticky fly traps dangled from ceilings in our farmhouse; one even hung over the kitchen table. Not at all appealing. But I’d rather see a dead fly than have one land on my dinner plate. In the barn, biting, swarming flies were a constant problem. For cows. And for humans.
But why were these thousands (maybe even millions) of flies here, on these church and cemetery grounds on a sunny late April afternoon, the first warm weekend of the season in Minnesota? There were no cattle (although the occasional piles of deer and other animal poop). There was no food.
The insects didn’t swarm the entire grounds—mostly just the area between the two historic church buildings and along the edge of the adjoining cemetery.
Once I got past the fly territory, I enjoyed my time at Valley Grove. It’s a beautiful place of quiet, of peace, set high atop a hill with lovely rural vistas. There are hiking trails and history in the cemetery (and churches when they are open). Generations of families are buried here. And there are oak trees, including one held together by thick chains in the corner of the cemetery.
This place holds stories. And now it holds one more story—the mystery of the fly invasion.
