Female Heptageniidae (March Browns, Cahills, Quill Gordons) Mayfly Dun

View 10 PicturesThis specimen is really strange, very different in form from any other mayfly I've seen. Unfortunately it was found alone crippled in an eddy and in pretty bad shape, and I couldn't find any others like it.

Agnetina capitata (Golden Stone) Stonefly Adult

View 8 PicturesThis stonefly emerged in my aquarium, and unfortunately I severely damaged its wings just trying to catch it. It's still an interesting specimen, especially since I was able to also photograph the nymphal shuck (

Here's an underwater view of the pupal shucks of several already-emerged Brachycentrus numerosus caddisflies.

Most often it describes the last nymphal or pupal skin exited during emergence into a winged adult.) it emerged from. I was surprised by just how light it was shortly after emerging. I photographed it a couple days later when it had darkened considerably; it was a pale, almost pastel yellow at first.

Sweltsa onkos (Sallfly) Stonefly Adult

View 8 PicturesI'm just guessing this is Chloroperlidae, since it's little and yellow. If anyone has a less haphazard identification, feel free to post it.

Female Ephemera varia (Yellow Drake) Mayfly Dun

View 7 PicturesThis yellow drake dun hatched out of my aquarium over a month before her brethren in the wild are slated to emerge. She seems a bit small, and that might be the reason.

Dun: Mayflies have two adult stages. They first emerge from the water as duns (scientifically known as the subimago stage). They then molt into the spinner (imago) stage, in which they mate and die. Sometimes the word "dun" is confusingly used to refer to a brownish gray color in fly tying materials.
