A predator can be defined to differ from a parasitoid in two ways: it kills its prey immediately; and it has many prey, captured over its lifetime, where a parasitoid's larva has just one, or at least has its food supply provisioned for it on just one occasion.
Može se definisati da se predator razlikuje od parazitoida na dva načina: on ubija svoj plen odmah; i on ima mnoge plenove, uhvaćene tokom njegovog životnog veka, dok parazitoidna larva ima samo jednog, ili bar ima svoj izvor hrane obezbeđen samo jednom.
