Final Summer Bug Count on Byrne Creek Reveals Some Beauties

Byrne Creek Streamkeepers finished a third and final summer weekend of bug sampling this morning, with samples from the last three of nine sites that we've been sampling twice a year for at least ten years.

These bug surveys give an indication of water quality, using a standard methodology in The Streamkeepers Handbook, which can be downloaded from the Pacific Streamkeepers Federation. Unfortunately, Byrne Creek rarely rises above the "poor" level, as it receives a lot of polluted runoff from its urban environment.

Here are a few of the more rare aquatic bugs (larval stage) that we found in the creek this summer:


Crane fly


Caddis fly
