Suppose the bushes the beetles feed on are spread widely over a mountain range. The beetle population will become very large as a result. but individual beetles feed mostly on a few nearby bushes throughout their lifetime.they do not travel so far.so in this huge population of beetles , sub populations in neighbourhoods will be formed.when populations are partly, not completely separated then these sub populations are formed.
