Pear Slug Sawfly
A cosmopolitan sawfly whose slimy, slug-like larvae skeletonize leaves of cherry, pear, and plum. Heavy infestations cause premature leaf drop.

October Caddis
A large orange-bodied caddisfly that hatches in autumn on western North American rivers. It is one of the most important late-season food sources for steelhead and salmon.

October caddis larvae build massive cases from pebbles and can be so abundant that they visibly alter the streambed substrate.
