The rate measured by generations is not that much different from other organisms. My point is that the changes I describe are demonstrated vividly, insects change proteins relatively quickly to deal with change but they do not change phenotype.
In fact while insects can adapt biochemically rather quickly, their basic layout and structure are very stable over millions of years thus making my point.
How can you say that? When have you heard last of a lioness that had 100 cubs, several times, each year?

Their basic structure and layout are stable over the years (except in size) because the features pass the tests of natural selection. The insects' basic shape is not challenged as much as its biochemical weapons and features.
