Okay kiddo, have you heard of fishing before? Well, when people go fishing they use something called a fishing lure to attract and catch fish. An artificial fly is a type of fishing lure that looks like an insect, but it's not actually real.
So, how do you use an artificial fly to catch fish? First, you tie the fly onto a fishing line, which is the string used to cast the lure out into the water. Then, you flick your wrist and "cast" the fly out over the water, letting it land with a little splash. This imitates how a real insect would land on the surface of the water.
When a fish sees the artificial fly floating on the water, it thinks it's a real insect and tries to eat it. The fish will bite the fly and get hooked on the fishing line. This is how fishermen catch fish using artificial flies.
There are many different types of artificial flies, each designed to look like a different insect such as a mayfly, caddisfly, or even a grasshopper. Some flies are designed to float on the surface of the water, while others are designed to sink down below the surface.
So, there you have it, an artificial fly is a fake insect used to catch fish when you go fishing!
