For one thing, most birds are a >lot< heavier than insects, which have 
significantly different aerodynamic properties from birds. The origin of 
flight in insects cannot be closely related to the origin of flight in birds 
and is pretty much irrelevant to it. I don't know why you even bring this up, 
except to add a straw man to your list of "flaws" in my reasoning.
