This common name refers to only one order.

Insect Order Lepidoptera

These are pretty much always called Moths.

The order Lepidoptera includes both butterflies and moths, but moths are the most important to the angler because so many species spend part of their lives underwater. These aquatic species are similar in many ways to caddisflies.

Many species, of course, are not aquatic at all.

Geometridae (Inchworms) Moth Larva

View 6 PicturesI caught this inchworm lowering itself to the surface of a trout stream from its silk thread. I saw a couple others floating on the surface, so it's likely the trout were familiar with them.
