Alloperla (Sallflies) Stonefly Adult

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.) early in the morning. There was also a yellow one with them, which I assumed was a different species. Now that I've seen how this one started changing from green to yellow, I have to wonder if they weren't the same species and the yellow one was just older.

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 (

I photographed it a couple days later when it had darkened considerably; it was a pale, almost pastel yellow at first.

Female Hesperoperla pacifica (Golden Stone) Stonefly Adult

View 13 PicturesMy blurry photo at first makes it look like there might be a distinct notch in the subgenital plate of this specimen, but that's not the case -- just a poor photo. That's important to the ID.

Female Calineuria californica (Golden Stone) Stonefly Adult

View 17 PicturesI caught this female in the vegetation on a trail about 50 feet above the stream. The coloration on its head differs from that of a male I collected recently on a nearby river, and from another female I collected on the same river. But it still keys out confidently to Calineuria, and californica is the only species of that genus in the area.
