Idahoans can expect to see Mormon crickets for a little longer than usual this year. And this summer’s outbreak is just a taste of what’s coming next year. A cool, moist spring delayed some hatching, and population levels peaked about three to four weeks later than normally expected.
Mormon cricket populations surge roughly every 15 to 20 years before succumbing to predators and cold weather, but their numbers have been steadily increasing in the past few years.Mormon crickets can devastate crop fields, reduce feed for livestock and grazing wildlife, and damage rangeland and cropland ecosystems. But the insects are an important part of the broader ecosystem.
In addition to being food for birds, Mormon crickets break down plant material and release important nutrients, such as carbon and nitrogen, back into the ground.
