Not all insects in Montana are bad. In fact, some of them are extremely helpful. Most people have a fear of insects, but if you leave them alone, they probably won't mess with you either.
I live in Manhattan, not far from the Gallatin River and Missouri Headwaters State Park...
A bird? A flying bug? A small, fluffy bat? I didn't know what the heck flew past my face the other day. Turns of it's something called a hummingbird moth. They're a thing.
It’s bad enough having to swat away a single bug, but an entire swarm? If you’re anywhere near the Missouri River that’s just something you might have to contend with – these “bugnadoes” form in areas with high volumes of water, particularly after flooding has occurred.
