Elk Hair Caddis

[Frenchcreek]

Just wondering if anyone has scientific/entomology information (or access to) about the family and genus of the Caddis we encounter on the Bow and other local streams, Livingston, upper Highwood, upper Oldman etc. I usually fish a lighter coloured body , (light olive/grey) and wing in the spring, some size 12, mostly 14, some 16,  a darker body (brownish/olive) colour in the fall, mostly size 14, some 16. For hackle I use a light ginger for spring and a light brown dyed or olive dyed grizzly.
