What is the point of hornets and wasps in the world?

Question

i just was wondering that and it is bugging me

Answer 1

as annoying as these insects are, all of them have a purpose to keep the universe intact. a few days ago i saw a wasp dragging a spider across the outside of my house. the spiders keep the population of mosquitos and other insects at a reasonable place. in return the wasp do the same with spiders. and other types of bees pollinate the flowers to keep them growing without their help we would not have any flowers or vegetables. the grass would die,as well as trees. the earth would become basically just dirt.
