Whitlock's Bright Spot Green Inchworm imitates the green inchworms that nest in trees. They usually appear for a few weeks in June and hang from the tree branches by a silky thread. They often fall into the streams making for a great chunk of protein. This Dave Whitlock pattern has a foam body that floats like a cork hits the water like a natural. The Bright Spot Inchworm works great on panfish as well as trout too.
