Gary LaFontaine regarded this species as very important in the West, and wrote of it in Caddisflies:

A. grandis is one of those special insects that is worth making the focus of a fishing trip because it gets the best trout in a river interested in feeding.

It owes much of its importance to its large size.

Arctopsyche grandis Fly Fishing Tips

Swisher and Richards remark in Selective Trout that imitations of the large adults make good searching patterns (Searching pattern: Any artificial fly pattern used when trout that aren't feeding selectively on anything in particular. A searching pattern may be an attractor or an imitation of something specific that the fish might favor even though it's not currently hatching.).
