Healdsburg, CA Posts: 356 | These are relatively uncommon in the Russian River. They are more common in its tributaries. Typically they are found in fast glides or riffles. They can be confused with Pteronarcella or other species of Pteronacys but Pteronarcella have a rounded pronotum and gills on the third abdominal segment while the only other known species of Pteronarcys in the area, Pteronarcys princeps has a less pointed pronotum. | |

Oscoda, MI Posts: 2611 | Love these big guys! Not sure if our species is the same, ours are pretty much black, and up to a size 2! And you practically have to dig into a log to find them, they like to crawl into crevices in wood. The adults are pretty impressive too! Jonathon | |
No matter how big the one you just caught is, there's always a bigger one out there somewhere... | ||

Healdsburg, CA Posts: 356 | Jonathon - The species are different, but pretty much similar superficially. As far as habitat goes ours seem to prefer a bottom of large gravel and cobbles. The adults are impressive and pretty poor fliers. They just lumber along. | |
