  Good question!
  
  Actually carnivorous plants still photosynthesis to gain their energy, they eat insects as a subsidy to gain nutrients such as nitrogen. So technically as they dont gain energy from the insects the are classes as Autotrophic!
  
  Its not always insects either sometimes other unsuspecting animals might fall in! http://www.youtube.com/watch?v=NJCaG4tOaAU
