Absolutely. 

Insects are one of the most abundance (visible) life(forms) on (this) Earth - because they live and work with (Mother) Earth. Human see insects as dangerous 'enemies' , (useless, destructive, scary, creeping-crawling,...) competitors (for food) and insignificant parts of (Mother) Nature. 

Human is WRONG as Time will tell: 'human struggles to master Nature' but 'insects work for Nature'.

Leave some weeds for insects to feed on and let them do their work for Nature and for us.

[I could also say much the same thing with 'micro-organisms' (bacteria, fungi, yeasts, ... ;-) ]
