Have you considered two other possibilities?
1. the mouths of insects were well adapted to feeding upon whatever they ate
in the 100 million years prior to flowers? (If they weren't then the insects
would have starved)
2. flowers evolved to match what was available at the time, namely, insect
mouth parts which were adapted to eating other thing.?
