| Grants Pass, OR Posts: 305 | This is one of the Rhyacophila betteni group. The R. betteni group consists of over 20 widespread, western species; common in small to medium, rocky trout streams. | |

 Administrator Bellevue, WAPosts: 2737 | Thanks Dave. Would it be worth sending you these last two Rhyacophilas for species IDs, or are the individual species too poorly described to key out? | |

| Grants Pass, OR Posts: 305 | Jason - I doubt I can place species names on the larvae. We are still working out the details of the adults. If you preserve material in 90%+ ETOH you can submit to the Barcode of Life Database (BOLD) for dna analysis which is very useful for future larval associations. | |
