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.

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

It is commonly held that clingers are flattened to make their lives better adapted to faster water. Their teardrop shape is certainly a classic symbol of aero and hydrodynamic perfection, so there must be some connection, right? It seems to me that such ideas show a complete misunderstanding of the hydraulic reality in which they live. Current is negligable even in the fastest a few mm. from the surface of solid objects. In fact, it is actually quite calm. I've observed baetids clinging by their tippy toes to the tops of rocks in fast riffles with no apparent effort, often next to clinger species that look like they're hanging on for dear life. What if clinger nymphs are flattened not to hold their place in fast currents but rather to facilitate movement in their ecological niche of the cramped spaces under and between cobble or crevices in other substrate types?

It is also thought that the gills of some species form ''suction'' to hold them in place. Since suction is a phenomena of vacuum creation in the atmosphere, how are these nymphs accomplishing this underwater? Is it their ultra delicate gills that hold them in place or a firm claw grip? The horizontal sprawl of the legs masks this as the gills stay in place until the legs brake free. Exposed to the air, the gills seem to laminate against the rock, just as crepe paper would if first held underwater before a rock was lifted out into the air from underneath it. However, underwater their gills behave like the crepe, flowing freely. They are performing their function as gills not suction cups. I find it hard to believe they evolved the way some think merely so they can make it more difficult for humans to pluck them from rocks in the atmosphere. How is it these mighty structures that defy our attempts to pry them from the rocks curiously fall off so easily when prodded for inspection a few seconds later in a tray or jostled in a container on the way home?

Even many scientific papers have encouraged these dubious beliefs so it's not just angler myth... And they go unchallenged... Thoughts?

The hatch often occurs during high water (just after peak) so you sometimes have limited visibility during the hatch. Also - I believe that they can occur above 7000 feet.

Love ths site.

While the Grannom Caddis and Apple Caddis are both from the Brachycentrus Genus, they are seperate "species". I believe much confusion is caused by some who refer to both as the "Grannom". Grannom (species: numerosus) is not the same color, nor does it hatch the same as the Apply Caddis (speicies: applachia). Pupa of the Grannom have a dirty olive, to dark olive body, with brown wing pads, and a brown shuck.They often hatch mid morning. The Apple Caddis Pupa is a light brighter olive, and a amber wing pad and amber to ginger shuck. Apple Caddis tend to hatch later in the afternoon. While size might be the same, the coloration of the adults have a completely different look. Apple Caddis adults have a very light colored wing, and a light (apple green body color). Grannom adults have a brownish wing with a body of dark olive, mixed with brown to black coloration. I have further noticed that the Grannom seem to hatch over much of the stream while Apple Caddis seem to hatch closer to shore. I'm just trying to clear up the problem of some calling both the Grannom, which leads to much confusion.
