****Animalia

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.

Male Baetis (Blue-Winged Olives) Mayfly DunMale Baetis (Blue-Winged Olives) Mayfly Dun View 14 PicturesThis dun molted most of the way into a spinner (though the wings got stuck) the evening after I photographed it, so I took some more photos of the spinner.

I found a female nearby, probably of the same species.

Brachycentrus (Grannoms) Caddisfly PupaBrachycentrus (Grannoms) Caddisfly Pupa View 10 PicturesThe green blob contained in this case is a pupa in the early stages of transformation from larva to the final stage we generally picture and imitate. This specimen and several like it were fixed to a rock I picked up, and each one had the front of its case sealed off, protecting the helpless pupa from predation. It's neat to see the insect part-way through such a radical transformation.

It was very hard to extract this thing from its case, so there's a bit of extra goo near the head from where I accidentally punctured it.
