First things that come to mind: soil would be quickly decimated. Without the many insects that are relied on for their decomposition powers and place in the soil food web, most soils would lose their nutrients and structures quickly.
Birds populations would suffer immensely and quickly with the loss of insects as a source of food.
So, so many crops and plants would be completely lost without bees to pollinate them.
Basically, it'd be bad!
Thanks for your answers @metaphortune, As you pointed out it would be bad. It would, however, be hard to predict the intensity of these consequences, their sequence and their timelines.
This question was inspired by this post in Business Insider, which illustrates some of the possible and would-be scenarios.
One interesting follow-up question we could ask is: What could possibly cause all the insects to vanish? What do you think?
