Piercing and sucking insects are a type of bug that feed by piercing plants or animals and sucking out their fluids. Here's a simple explanation:

• How They Feed: These insects have special mouthparts that look like tiny needles. They use these needle-like structures to poke holes in leaves, stems, or even animal skin. Once they make a hole, they suck out the juices or blood, similar to how you would drink through a straw.


• Examples: Common examples include:
  
  
  
  • Mosquitoes:They pierce human or animal skin to suck blood.
  
  
  • Aphids:They pierce plant stems to suck out the sap.
  
  
  • Stink Bugs: They use their mouthparts to pierce and suck juices from fruits and vegetables.


• Impact: These insects can cause damage to plants by draining their nutrients, which can make the plants weak and unhealthy. When they bite animals or humans, they can sometimes transmit diseases.
