What effects do floods have on insects?

Tad,
Odd, my reading in the past was the opposite.....that tricoptera were most vulnerable to stream pollution.....?

Can you provide your source?

Thanks

Byron,
My source was a fishing guide from the ArkAnglers fly shop in Salida, Bill Dobson.

Here is an article from Karl Blankenship where he states that caddis are more pollution tolerant than mayflies or stoneflies.

I have noticed that other streams in Colorado with mine pollution, heavy metals, in the water tend to be dominated by caddis. It may be that mayflies are more tolerant of different types of pollution.

Regards,
Ted
