Animals
This common name refers to only one kingdom.
Animal Kingdom Animalia
These are pretty much always called Animals.
Metazoa is the kingdom of animals. Worms are metazoans and so were the dinosaurs. Trout and mayflies are metazoans. You are probably a metazoan.
See Arthropoda for most of the invertebrates trout eat, or skip straight to the insect orders Ephemeroptera (Mayflies), Trichoptera (Caddisflies), or Plecoptera (Stoneflies), which are the three most important.
The non-arthropod classes are listed on this site only to hold pictures, so far, and I haven't put much information up yet about them.

Arcynopteryx compacta Stonefly Nymph
View 11 PicturesThis large Perlodidae stonefly was a strikingly bright yellow color, moreso than any other insect I've seen. I didn't enhance it much. I tried identifying its genus and came up with Arcynopteryx, which lives a couple thousand miles from where I collected this one, so I'm stuck.

Male Leptophlebia cupida (Black Quill) Mayfly Dun
View 6 PicturesThis Leptophlebia cupida dun was extremely cooperative, and it molted into a spinner for me in front of the camera. Here I have a few dun pictures and one spinner picture, and I've put the entire molting sequence in an article.

Rhyacophila (Green Sedges) Caddisfly Pupa
View 11 PicturesI collected this pupa and several like it from the same stream and on the same day as this larva. I suspect they're the same species. Every pupa I collected was in a brown casing like the one shown in one of the pictures below. I cut this pupa out of its case after a picture so you can see more details. It is close to but not fully developed.
