Inherite template might help to explain several different animal behavior patterns.
Caddis fly larvae create clothing for themselves in the form of hard cases made of grains of sand, daubs of mud, cut pieces of leaf, and such, glued together with their own silk. All larvae of the same species of caddis fly construct cases of a particular, identifiable pattern. If a piece of the case breaks off, or is removed by an experimenter, the larva will go out and get or cut something else of the same shape with which to replace the missing piece. Inherited templates might help explain how individuals of a certain species of caddis fly build such similar cases, and how they choose particles or cut leaves of a particular size ans shape so as to maintain the pattern of their case structure.
