Skip Morris BH October Caddis The October caddis is the biggest caddis on western rivers, and appears in late September into early November when not much else is hatching to compete with it this can be one critical caddis. Skip's Brick Back October Caddis imitates the important pupa stage. Fished dead-drift below a strike indicator to imitate failed pupa or pupa drifting as they regain their motion after so long in a shell, or cast upstream to sink and then swung towards the bank like a swimming pupa, the Brick Back can move lots of trout on a good day, some big ones among them.
