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.

A Brachycentrus "Apple Caddis" pupa scoots around in the surface film.  Apparently it had some difficulty emerging, so I was able to slip my camera underneath it and take a picture from below.  In this picture: Caddisfly Species Brachycentrus appalachia (Apple Caddis). From the East Branch of the Delaware River in New York.

Missing genera (from missing list)
Posted by AndyV on Nov 8, 2022 in the family Caenidae
Latineosus, Sparbarus, Susperatus should all be included in the genera that aren't included (I think).

I've seen hatch charts (e.g. DNR hatch chart for SE MN) stating mid-May til the end of July vs June (from this site). Can anyone confirm?

Hi Jason! Do you have a picture of the (acentrella-miniature BWO nymph) on the site? I've been fishing them and wanted a better idea of how they look.
Thanks,

ReplyPlectrocnemia missing
Posted by AndyV on Aug 25, 2022 in the family Polycentropodidae
I believe this is missing from the list. Unsure of it's importance. However, they was a study on Plectrocnemia conspersa relative to trout populations in Ashdown Forest streams [Schofield et al. (1988)].
