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.
Did You Know?
October caddis larvae build massive cases from pebbles and can be so abundant that they visibly alter the streambed substrate.
Grape Flea Beetle
A small, metallic dark blue beetle with enlarged jumping legs that feeds on grape buds and young foliage. It can cause significant economic damage in vineyards by destroying developing buds.
Did You Know?
Adults emerge in early spring to feed on swelling grape buds, and a single beetle can destroy multiple buds before leaves fully develop.
