An insectivore is a type of carnivore with a diet that consists chiefly of insects and similar small creatures. An alternate term is entomophage, which also refers to the human practice of eating insects.

The first vertebrate insectivores were Amphibians. When they evolved, 400 million years ago, the first amphibians were piscivores, with numerous sharp conical teeth, much like a modern crocodile. The same tooth arrangement is however also suited for eating animals with exoskeletons, thus the ability to eat insects is an extension of piscivory.

Although individually small, insects exist in enormous numbers - they number over a million described species and some of those species occur in enormous numbers. Accordingly insects make up a very large part of the animal biomass in almost all non-marine, non-polar environments. It has been estimated that the global insect biomass is in the region of 10¹² kg with an estimated population of 10¹⁸ organisms. Many creatures depend on insects as their primary diet, and many that do not (and are thus not technically insectivores) nevertheless use insects as a protein supplement, particularly when they are breeding.

Andrew Robert MacFarlane Nielsen (born October 6, 1982) is an American rapper, known by his stage name MC Lars. He is the self-proclaimed originator of "post-punk laptop rap". He was one of the first underground rappers to sample and reference post-punk and emo bands.
