Insects and angiosperms...
What do the insects do when the angiosperms appear? Not much. Whatever diversification took place, it apparently occurred inside the individual family level because if we simply look at the numbers of families against time, there is no particular explosion associated with the angiosperms. However, we know that insects are important to angiosperms both as pollinators
- (no, this is not a fossil- we haven't caught a bee on a flower in the fossil record yet). But, we certainly have found things, for example, like leaf miners feeding on an angiosperm. The individual mine patterns help identify individual groups of leaf miners in the present day. We can determine that leaf miners of modern aspect appeared very quickly after angiosperms appeared.
